The primary colors of light are red, green, and blue. These three colors are fundamental because they can be combined in various proportions to produce all other colors visible to the human eye. This system is known as additive color mixing, where combining red, green, and blue light in equal intensities produces white light. For example, mixing red and green light yields yellow, green and blue produce cyan, and red and blue produce magenta. This RGB model is used in devices like computer monitors and televisions to create a wide range of colors
. In contrast, the primary colors for pigments or inks (subtractive color mixing) are cyan, magenta, and yellow, which differ from the primary colors of light
. The traditional art primary colors-red, yellow, and blue-are different and less precise in terms of color mixing and are mainly used in painting and art education
. Thus, for light specifically, the primary colors are:
- Red
- Green
- Blue
These are the basis for how human vision perceives color and how electronic displays generate color images
