Yellow is any color of light that stimulates both the red and green cone cells of the retina, but not the blue cone cells. Light with a wavelength of 565-590 nanometers is yellow, though light with both red frequencies and green frequencies, such as mixing orange and lime light, or red and green light, is also yellow. It is one of the subtractive primary colors, and its scientifically defined complementary color is blue. However, because of the characteristics of paint pigments, painters traditionally regard its complement as purple.
The CMYK system for color printing is based on using four inks, one of which is a yellow color. This is not in itself a standard color, though a fairly narrow range of yellow inks are used.
