Red Blue
Red Blue
Why can’t the primary colors (red, blue, and yellow) be created using any other combination of colors?
In art, the three primary pigment colors are red, blue, and yellow. According to books on painting, these pigments can’t be created using any other combination of colors, Is this true and, if so, why?
The color of light is determined only by its wavelength. So there is no primary color from the standpoint of a physicist. And the chemistry of pigments is so complicated, I can’t see how you could have primary pigment colors. Maybe the physiology of the eye is what determines the primary colors.
Let’s take blue as an example. Blue pigment appears as it does because it reflects ONLY blue wavelengths of light. If we mix ANY 2 or more pigments together, the resulting mixture will reflect more than one color and the eye will NOT see this as pure blue. Instead it will see some of EACH of the pigments in the mixture.
