Which term describes a dorsal-ventral color pattern that helps camouflage?

Explanation:
Countershading is the pattern where the top side of an animal is darker and the underside is lighter, helping to blunt the effects of light from above and below. This makes the animal harder to detect when viewed from either direction in the water, because the shading matches the surroundings as light falls or is reflected. Cryptic coloration is a broader idea of camouflage, but the dorsal–ventral gradient specifically described here is countershading. Drag is unrelated to coloration, and Chondrichthyes is just a taxonomic group, not a coloration pattern.
