FAQ
Frequently Asked Questions
No, they are different systems. For light (additive color), the primaries are Red, Green, and Blue (RGB). For paints/pigments (subtractive color), the traditional primaries are Red, Yellow, and Blue (RYB), though modern printing uses Cyan, Magenta, Yellow, and Key (black) (CMYK).
Green is a primary in the RGB additive model because it is one of the three fundamental wavelengths of light that our eyes perceive directly and combine to create other colors. In subtractive mixing (paints), pigments absorb (subtract) light. Green can be created by mixing blue and yellow pigments, so it is not a primary in the RYB system.
In standard color theory models, the concept of 'primaries' is defined as a minimal set of independent colors from which a wide gamut (range) can be mixed. Most models use three due to human trichromatic vision. However, some specialized or theoretical systems may use more for specific purposes, but three is the standard for general color reproduction.
No. In color theory, black and white are considered achromatic (without hue). Black is often the absence of light or a mixture of all pigments, and white is the presence of all light or the absence of pigment. They are used to tint, shade, or tone the primary and secondary colors.
