Richly colored illustrations can have quite an impact on the viewer. There’s an almost psychedelic quality to drawings like these, giving you the impression that you’re glimpsing another world.
Contrast the effect with that of black-and-white illustrations. It takes another set of artistic skills to color with only hues of black, white, and gray. While these drawings might seem muted when compared to their vibrantly colored counterparts, they can still manage to leave a strong impact.
