Color
Visual perception of the light spectrum
"Colorful" redirects here. For other uses, see Color (disambiguation) and Colorful (disambiguation).
Color (or colour in Commonwealth English; see spelling differences) is the visual perception based on the electromagnetic spectrum.
Though color is not an inherent property of matter, color perception is related to an object's light absorption, reflection, emission spectra, and interference.
Where does color come from in paint
For most humans, colors are perceived in the visible light spectrum with three types of cone cells (trichromacy). Other animals may have a different number of cone cell types or have eyes sensitive to different wavelengths, such as bees that can distinguish ultraviolet, and thus have a different color sensitivity range.
Animal perception of color originates from different light wavelength or spectral sensitivity in cone cell types, which is then processed by the brain.
Colors have perceived properties such as hue, colorfulness (saturation), and luminance.
Colors can also be additively mixed (commonly used for actual light) or subtractiv
