Number: 358/520
Name: Facsimile and static presentation processing > Natural color facsimile > Color correction > Hue, saturation and luminance
Description: Subject matter wherein the color correction is modified by (a) changing the dimension of color that refers to a scale of perception ranging from red through yellow, green and blue, and circulates back to red; (b) a pure color; (i.e., one not mixed with white light); or (c) a photometric quantity of light radiation.
