Ever wondered “what are the Primary Colors?” Contrary to what we’ve been taught in middle school, 2 distinct categories of primary colors exist.
The only two fundamental ways to create color are additive primary colors and subtractive primary colors. Both methods employ primary colors, which are unmixable colors that are used to produce all the colors of the rainbow.
It might seem way to define what are the primary colors. Red, yellow, and blue are the 3 fundamental colors.
However, the reality of the matter is much more complicated than most notions that first appear to be straightforward.
Moreover, even though the books don’t precisely mislead you, they don’t provide the complete picture either.
Let’s dive into this post on ”what are the primary colors?”
1. What Are the Primary Colors?

To answer what are the primary colors, let us define what these are made up of.
A group of primary colors are made up of colorants or colored lights that may be combined in different ratios to create a spectrum of hues. This is the key technique used in, among other things, electronic screens, color printing, and artworks to provide the impression of a wide spectrum of colors.
A proper blending model that accurately captures the mechanics of how light reacts with material surfaces and, eventually, the retina, may anticipate perceptions related to a specific mixture of primary colors. Some items are bright and emit their inherent lighting; all the other materials must reflect light into human eyes to be viewed.
As additive numerical components of a color space or as fundamental experiential categories in fields like psychology and philosophy, primary colors can also be theoretical not necessarily actual.
Psychophysical colorimetry tests, which are the cornerstone of comprehending color vision, provide a clear definition and factual foundation for color space primaries. Although necessary fictitious, the fundamentals of certain color spaces are comprehensive in terms of their constituents balanced by nonzero primary brightness coefficients that are, there isn’t a way those primary colors could be represented physically, or perceived.
Despite not being a quantitative description in and of itself, phenomenological explanations of basic colors, such as the psychological primaries, have been employed as the conceptual foundation for practical color applications.
Since there isn’t a single set of primary that can be regarded as the standard set, sets of color space primaries are often random. Primary colors or light sources are chosen for a specific application based on a combination of practical concerns including cost, durability, accessibility, and personal choices.
The idea of fundamental colors has a lengthy and intricate history. Various fields that research color has changed their primary color preferences over time. Philosophy, art history, color order systems, and scientific studies of the physics of light and color perception are among the disciplines that have contributed to descriptions of what are the primary colors.
Red, yellow, and blue are frequently used as the fundamental colors in art instruction materials, with the implication that they may be mixed to create any color.
However, no collection of actual colorants or lighting can combine every shade imaginable. The three fundamental colors in physics are usually red, green, and blue, named for the various types of photosensitive chemicals found in cone cells. This is not the enough to know what are the primary colors, so scroll more to get more detail.
2. Types of Primary Colors
After knowing types of colors you will easily understand what are the primary colors. Simply put, red, yellow, and blue are your basic colors if you’re referring to painting. But your fundamental colors when discussing physics and light are red, green, and blue.
The perplexing paradox is caused by the existence of two distinct color theories, one for colored light and the other for “material colors” like those employed by artists. The terms “additive” and “subtractive” color schemes refer to these two philosophies.
A Professor of Color Science at the University of Leeds in England claimed that light entering our eyes is how we can see. Our eyes receive light in two different ways: directly from a colored light source and reflected from objects. Additive and subtractive color mixing are the results of this.
Both systems complete the same job, which is to modify the responses of the three different types of cone photoreceptors found in our eyes. These have almost equal sensitivity to red light, green light, and blue light.
By regulating the proportions of red, green, and blue light that humans perceive and hence nearly immediately mapping to the visual reactions, the additive primaries do this extremely directly. Red, green, and blue light are likewise modulated by the subtractive primaries, but less effectively.
Let’s discuss those differences, but first, a word of caution: everything you think you know about what are the primary colors is going to alter.
2.1. Subtractive Color Mixing
When we combine paint or dyes, we produce subtractive color mixing. It has to do with all the colors we see in non-emissive materials like inks, paints, plastic materials, fabrics, and so on. Due to their ability to reflect incident light, certain materials may be seen. Take a sheet of white paper as an example; it reflects nearly all of the visible spectrum wavelengths. Now cover the paper with a layer of yellow ink. The blue wavelengths are absorbed by the yellow ink while the others, which are perceived as yellow, are reflected.
In this instance, we begin with white light (all wavelengths will reflect light) and begin to remove light at different wavelengths as we add the primary colors, as opposed to being additive.
The chemical composition of the items and their colored light-reflecting properties are hence what ultimately determines the differences across color systems. While the subtractive color system deals with intangible artifacts like textbooks and artworks, the additive theory is focused on things that produce light. According to Raiselis, subtractive colors are those that radiate less light when combined. In a subtractive color system, light is captured while mixing paints, creating colors that are darker and duller than the original colors.
Since they can hardly be created by mixing paints, these three colors define what are the primary colors.
Red, blue, and yellow are the primary colors that may be mixed to make other hues of the rainbow in the physical world. But keep in mind that the subtractive color systems of primary colors for TVs, mobile devices, computer screens, and more all adhere to Newton’s light-emitting system, so their primary colors are red, green, and blue. This is especially important if you’re discussing anything tech-related, which is what most of us are doing these days.
2.2. Additive Color Mixing
Newton made a ground-breaking discovery. He was able to mix the red, green, and blue (RGB) colors of a reflected rainbow to produce white light by combining prisms and reflectors. Since these were the essential components required to produce pure, white light, Newton designated those three hues as the “primary” colors.
An additive color system includes those that, when combined, produce more light. Imagine three flashlights emitting distinct circles of light over a wall to quickly understand additive light. The connection between the two spotlight rings is brighter than each of the individual circles, and the junction of a third spotlight ring will be much brighter. Since we add light to each combination, we refer to this type of mixture as an additive color system.
According to Raiselis, the secret to comprehending additive color mixing is to picture each flashlight as being equipped with a transparent color filter – one red, one green, and one blue. For the RGB, the primary and secondary colors are red and green light and blue light which differs depending on the model.
There is a lighter blue-green form where the green light and blue flashlight circles cross. It’s cyan. The mixture of red light and blue is also lighter; it is a lovely magenta ink. Additionally, the red and green light combine to create yellow light, which is a lighter hue and a shocker to almost anyone who sees it! As a result, yellow may be created from red, green, and blue, making them additive colors’ primary colors. White light is created when red, green, and blue lights are combined. This is how the TV and computer screens operate.
Additionally, if you’ve ever been in a theater play, you may have noticed the red, green, and blue lights that act as the additive primary colors of the stage when you peeked from behind the drapery.
The simplest definition of additive color is when a light-emitting device, such as a TV or mobile screen, is used. The majority of gadgets emit three separate hues of visible light, which are combined when they are utilized. But depending on the primary colors, the gamut, or spectrum of colors that may be created from three additive colors varies. The additive color primaries, as Newton initially postulated, are red, green, and blue, according to the majority of publications, but Westland claims that things are far more complex than that.
The optical system includes receptors in the eyes that react positively to red, green, and blue light, but this is a myth. As a result, it is frequently said that the RGB model is the ideal model of primary colors. For instance, the maximal sensitivity of the long-wavelength sensitive cone is in the yellow light to a green light region of the spectrum, not the red light.
3. The Difference between Subtractive and Additive

After understanding what are the primary colors let us learn about the difference between their types?
Apparently, cyan, magenta, and yellow are the greatest colors to utilize if we only use three primaries, according to Westland. Remember that these are the primary colors that the big printing firms have recognized since they employ CMYK color models in their industrial equipment to create a wide variety of colors. It is unclear and shouldn’t be told that the subtractive primary is red, yellow, and blue (RYB model). It would be incorrect to believe that blue and red are just known by their fancy names, cyan, and magenta.
The names we’ve been giving our primary colors in coloring books and paint chips are alarming but real.
The subtractive color systems’ primaries are cyan, magenta, and yellow. “The terms “blue” for “cyan” and “red” for “magenta” are frequently misused. Other hues can be used as primary, but they won’t yield as many different color combinations.
The yellow primary governs the quantity of blue light reaching human eyes. While a relatively intense amount of yellow eliminates more blue light, a smaller amount of yellow primary color only removes a little bit of blue light from the initial white stimuli. The quantity of green light is controlled by the magenta primary color, while the degree of red light is controlled by the cyan primary. In contrast to additive primaries, which simply emit varying quantities of red, green, and blue, subtractive primaries do this by collecting distinct quantities of each color. Balancing the quantities of red, green, and blue light is essential.
Red and blue aren’t “pure” colors despite what we’ve been taught, they’re just not.
Magenta and yellow can be combined to create the color red. We can create all hues if we use the RYB or CMYK model, or rather virtually any other logical choice of three primaries—definitely not 3 reds!—but we cannot create all the colors. However, the CMYK model will give us the widest range of colors, so we may argue that it is the ideal subtractive primary, just as RGB is the ideal additive primary.
Additionally, blue isn’t as pure as you may imagine. Since it substantially absorbs in the lower 2/3 of the spectrum, it appears pure. The green and red portions absorb it. The regions of blue and green absorb red. As soon as we combine them, they start to absorb everywhere. Even if the combination could be purple, it will be gloomy and dark. These colors’ absorption spectra are excessively wide. Since cyan absorbs mostly in the red and green portions of the spectrum, respectively, it is preferable to utilize cyan instead of blue.
When magenta and cyan are combined, the red and green portions of the spectrum are absorbed, but the blue light is allowed to reflect visible light.
In conclusion, the best color schemes for subtractive color systems and additive color systems, respectively, are cyan-magenta-yellow and red-green-blue.
4. RGB Versus CMYK Color Model
For primary colors, there are two models. This information is also important for better understanding on what are the primary colors. They serve various functions and have various characteristics. These are what they are:
4.1. CMYK Color Model
Cyan, magenta, and yellow make up the CMYK Color model. Printing and painting both fit the bill. The CMYK model is a subtractive model, which means that colors are produced by soaking apparent light wavelengths. The wavelengths of light that are not absorbed are mirrored, and the color we perceive is created by this specular reflection.
The CMYK paradigm conceals some or all of the colors over a lighter backdrop, often white. The light that would ordinarily reflect is diminished by the ink. Since inks “deduct the shades of red, green, and blue from white light, a model like this is referred to as subtractive. White light without the red, green, or blue components is cyan, magenta, and yellow, respectively.
4.2. RGB Color Model
Color schemes in RGB Red, green, and blue are referred to as RGB. It applies to gadgets like computer screens and televisions. Since the RGB model is additive, colors are produced by adding together certain combinations of light waves, which is how colors are formed.
Because of the color components and how they react to the distinct degrees of red, green, and blue change from product to product, or even within the same technology over time, various appliances detect or replicate a particular RGB value differently. Therefore, without some sort of color correction, an RGB value doesn’t describe the same color across screens.
5. Traditional Red, Yellow, and Blue Primary Colors

Traditional color mixtures theory is more grounded on pigmented perception than in light physics. It doesn’t concern the dye manufacturers if, as the physicist claims, red and green light in combination form yellow light when they discover via research that red and green pigment in combination produces a grey, according to Snow and Froehlich’s explanation from 1920. Whatever the spectrograph may show about the interaction of yellow and blue light, the fact that yellow and blue pigments combine to form green pigment cannot be denied.
The impact of the Bauhaus, where Johannes Itten established his thoughts on color throughout his stay there back in the 1920s, and of his work on color has been ascribed to the universal popularity of instructing RYB as basic colors at post-secondary art institutions in the 20th century.
Since at least the 19th century, several authors have emphasized that red, yellow, and blue (or RYB) are the primary colors in art school materials.
The RYB primary are described in a wide range of modern educational texts as well. These sources include children’s books, art supply companies, paintings, and color schemes, among others. Materials for art instruction frequently state that all additional colors may be made by combining RYB primary.
6. What Is a Color Wheel?

A color wheel is a diagram that shows different color shades in a circle. It aids in illustrating color calibration and the connections between what are the primary colors, secondary colors, and intermediate/tertiary colors. Hex codes are used by digital teams to express precise color information.
Red, yellow, and blue is the main colors of the conventional RYB colors wheel. By combining basic colors you may get secondary hues like orange, green, and purple. Orange is made up of red and yellow. Green is made up of yellow and blue. Purple is made when red and blue are combined. You can recall this from your primary art class lessons about what are the primary colors.
Tertiary colors are then produced by combining secondary and primary hues. There are other variations of the color wheel, but many of them have these three mutually related displays of twelve colors.
Temperature of Colors
Warm colors may be found on the red side of the wheel while cooler colors can be found on the green side. These names for color temperatures are unchangeable. More nuanced color temperature correlations are relative, which means that relying on the connection to their surrounding hue, colors on the warmer side of the color wheel can be recognized as cold, and colors on the cooler side of the color wheel can be recognized as warm. Red, for example, is a color that may be both warmer and colder than other colors of the same shade.
We are mentally and culturally influenced by color temperatures because they assist us to evaluate how items appear to be arranged.
7. Vision for Color and Light Sources
The various spectrum elements of sunlight were referred to as “basic colors” by Isaac Newton.
Many color theorists disagreed with Newton’s conclusions. David Brewster argued that red, yellow, and blue light could be blended to create any spectrum shade in the latter part of the 1840s.
While Maxwell suggested making violet blue instead of violet, Thomas Young proposed red, green, and violet as the 3 main hues.
In “contemporary color science,” which finally characterized the experience of coloring about the three different retinal photosensitive types, Newton, Young, and Maxwell were all essential players.
Conclusion
What are the primary colors? Hope now you get the answer. White light results when all of the RGB model’s colors are combined. Green – Is it a Primary Color? Green is a primary color in RGB, yes. However, under the CMYK color model or the RYB color model, green is a secondary color created by combining cyan and yellow. Blue: Is it a Primary Color? Yes, it is a primary color in RYB and RGB. However, under the CMYK color model, blue is a secondary hue created by combining cyan and magenta. Do you think it was fun to read about what are the primary colors?
You must have found solace in this comprehensive explanation that dispelled every color myth you’ve believed since you were a youngster and in case you’re feeling a little panicked, coloring books have always been effective stress relievers.
