No one can deny the power of color. No other element can draw the eye quicker or more powerfully.
But color isn't perfect. It speaks to the visual part of our brain which is more ambiguous than the auditory part. Like words, black and white images communicate ideas much more clearly and more precisely. I've heard several theories on why this is, but I'm not sure anyone actually knows.
Above and below are two images from the Wandering Koala Adult Coloring Book. The book collects the Wandering Koala 80-page Giant #1, but strips out the color so the reader can add them himself. Or he can choose to enjoy the story in it's more raw form. Read it both ways and see which one draws you in quicker and tighter.
