Yellow is one of three primary colors, which means that it is one color only and cannot be made by mixing other colors. The shade of yellow may be lightened or darkened by adding additional colors, however. White can be added to yellow to make a paler shade, and adding orange or red will create a darker yellow.
Color (American English) or colour (Commonwealth English) is the characteristic of human visual perception described through color categories, with names such as red, yellow, purple, or blue. This perception of color derives from the stimulation of cone cells in the human eye by electromagnetic radiation in the spectrum of light. Color categories and physical specifications of color are associated with objects through the wavelength of the light that is reflected from them.
