Lab color space Scientific approach.
L*a*b* (CIELAB, LAB) color space describes all possible colors in an abstract three dimensional space
Each color is described with three coordinates:
L* = luminance a* = green-red component b* = blue-yellow component
L* (black to white)
b* (blue to yellow)
a* (green to red)
Theoretical L*a*b* color space In actual applications the Lab color space is reduced to available RGB spectrum
Colors visible for human eye in L*a*b* color space
Lab color space is far from being intuitive. It is however a precise, device-independent color definition used in science and industry. In Painter 7 you can define colors using Lab coordinates (see page 128).
