2.18 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 sub-colors red, green, and blue (rgb). Each sub-color's value can range from 0 to 255. Thus (255,0,0) is bright red, (130,0,130) 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
