The most commonly used method of obtaining color information in digital photography is the use of a [[Bayer filter]], invented by [[Bryce Bayer]] of [[Eastman Kodak]] in 1976. In this approach, a sensor that is sensitive to multiple wavelengths of light is placed behind a color filter. Traditionally, each pixel, or "sensel", is thereby assigned an additional light response curve beyond its inherent differential response to different wavelengths - typically the filters applied respond to red, blue and green, the latter being used twice as often based on an argument that the human eye is more sensitive to variation in green than any other color. Thus, the color image produced would preserve color in a way resembling human perception, and not appear unduly deteriorated in any particular color range.
