The primary colors red, blue, and yellow are considered as such because they cannot be obtained by mixing other colors. They allow to create a wide spectrum of colors by combining them in different ways, making them the basis of color mixing.
Long ago, people already believed that certain shades were the basis of all others. As early as Antiquity, Aristotle put forward the idea that there were fundamental colors from which all others derived. The modern idea of primary colors emerged during the Renaissance, when artists and thinkers attempted to define pure pigments that would allow for any hue in painting with the least amount of mixing possible. It was especially in the 18th century, thanks to theorists like Le Blon and Goethe, that the concept of a trio of primary colors became clearly established: red, blue, and yellow. This historical approach explains why these three colors are intuitively ingrained in our artistic culture as those that must be readily available to mix all others.
The subtractive synthesis of colors is the principle that explains how color works when we talk about paint, ink, or pigments. The thing is simple: at the beginning, imagine you have a source of white light that contains all possible colors. Every time you add a pigment color, you remove (or subtract, hence the name...) colors from that light. So, if you mix the three primary pigment colors, namely red, blue, and yellow, you gradually end up with black, because each pigment absorbs different parts of the light. Each pigment plays its role as a filter by absorbing certain shades and reflecting those that we eventually see. That's why in paints, making a color mix actually means removing parts of light, and it's thanks to this that we get so many shades on our paint palette.
For centuries, artists have relied on red, blue, and yellow to mix and achieve almost all possible shades. This trio is simple to use and allows for endless variations by combining just a few basic colors on a palette. Painters often favor these primary colors because they provide clarity, vibrancy, and manageable contrast. For example, Van Gogh and Mondrian enjoyed manipulating these raw colors to evoke strong emotions or create simple yet powerful compositions. In practice, it's like an essential toolbox for any artist: these three hues are enough to create a complete image from almost nothing.
There are two main ways to create colors: the subtractive method and the additive method. Subtractive primary colors (red, blue, yellow in the classic painting model, or cyan, magenta, yellow in printing) work by absorbing certain colors of ambient light. Each layer of subtractive color adds additional absorption, which means that mixing all these colors together results in black or a dull dark shade.
In contrast, the additive method is mainly about light directly emitted from a light source, typically on screens. The classic additive primary colors are red, green, and blue (RGB). By adding these lights together, you get increasingly lighter colors, up to white when the three primary lights are mixed in equal parts.
In short, the fundamental difference: in subtractive, you add pigments that progressively remove light to create colors, while in additive, you directly combine colored lights to achieve the final hue.
The three primary colors, red, blue, and yellow, are at the heart of many cultural and symbolic references. Red, for example, often represents strong emotions: love, passion, but also danger or anger. It's no surprise that it's found in many national flags or political symbols. Blue, on the other hand, tends to evoke something calm, serious, or spiritual, associated with the sky or the sea, and is often used to represent peace, trust, or authority (official uniforms, logos of serious companies, etc.). As for yellow, it often symbolizes the sun, joy, dynamism, or even wealth (some Asian countries associate it with imperial prosperity). These three colors go far beyond painting; they directly influence our way of interpreting emotions, ideas, or cultural symbols.
In modern printing, the subtractive primary colors used are cyan, magenta, and yellow (CMY model), and not the traditional red, blue, and yellow taught in artistic painting.
Isaac Newton was the first to identify the spectrum of colors by breaking down white light through a prism in the 17th century. However, he considered seven primary colors instead of three, also including indigo.
The additive color theory used in electronics and lighting has a different set of primary colors: red, green, and blue (RGB), unlike the traditional artistic system which employs red, blue, and yellow.
The colors red, blue, and yellow are often favored in art due to their strong visual contrast, which helps artists effectively blend the entire color spectrum.
The subtractive primary colors (red, blue, and yellow in the arts, or cyan, magenta, and yellow in printing) mix by gradually removing light, theoretically resulting in black. The additive primary colors (red, green, and blue) mix by adding light to create new shades, theoretically resulting in white when combined at full intensity.
The traditional artistic concept of primary colors—red, blue, and yellow—is historically rooted, but in practice, especially in modern printing and publishing, cyan, magenta, and yellow (CMY) prove to be more effective in generating a wide range of colors. The traditional artist's red and blue already contain several shades, which limits the achievable color spectrum.
Not necessarily. The concept of primary colors depends on historical, cultural, and technical contexts. While historically in the West, red, blue, and yellow have been widely adopted in painting and art education, elsewhere, different schemes and representations of colors may have been favored based on graphic traditions and available materials.
Yellow is generally perceived as very bright due to its wavelength, which is close to those at which our eyes have maximum sensitivity. Thus, yellow often appears more luminous, more vibrant, and more noticeable even in low light compared to other primary colors.
In additive synthesis, used for example in digital screens, the primary colors are red, green, and blue (RGB). This is explained by the biological functioning of our vision, where the retinal cones primarily respond to these three light spectra. Yellow, on the other hand, becomes a secondary color resulting from the mixture of red + green in this specific model.
