            As red from yellow or green from blue or purple

 

Chroma – Quality of color we distinguish a strong color from a weak color

             The degree of departure of a color sensation from that of white or grey

             The intensity of a distinctive hue

 

Value – That quality we distinguish a light color from a dark one

 

Relates to the way artists mix colors

It is hard to chose RGB to obtain pink or brown

Instead an artist chooses a pure hue or pigment and lightens to a tint of that hue

By adding white or darkens it by adding black

More generally he adds white, black and gray.

 

H = selecting a color

S = desaturating the color (adding white)

V = adding black
