Yellow

From Academic Kids

Template:Infobox color Yellow is the color of light whose wavelength is between 565 nm and 590 nm. The human eye also perceives some mixtures of differently-coloured lights, such as red added to green, to be the same color.

Yellow is one of the subtractive primary colors, and its complementary color is blue. However, because of the characteristics of paint pigments used in the past, painters traditionally regard its complement as purple.
