4.22 LAB: Remove gray from RGB Summary: Given integer values for red, green, and blue, subtract the gray from each value. Computers represent color by combining the subcolors red, green, and blue (rgb). Each subcolor's value can range from 0 to 255. Thus (255, 0, 0) is bright red, (l30, 0, l30) is a medium purple, (0, 0, 0) is black, (255, 255, 255) is white, and (40, 40, 40) is a dark gray. (130, 50, 130) is a faded purple, due to the (50, 50, 50) gray part. (In other words, equal amounts of red, green, blue yield gray). Given values for red, green, and blue, remove the gray part. Ex: If the input is: 130 50 130 the output is: 80080 Find the smallest value, and then subtract it from all three values, thus removing the gray. Note: This page converts rgb values into colors
