STEP THREE — Invert the colors of each separation:
In these examples I simply inverted the colors of each separation like a negative. Notice how the formerly “lighter” image on the left now shares similar hues to the original “darker” image. The same holds true for the formerly “darker” image on the right. That is because these two hues are opposite on the color wheel. Sometimes oppsite colors can alter our ability to see the colors as they might be if they were isolated from one another.
