Problem: David was interested in the coloration of ocean's water. To understand the phenomenon he first observed the color of water at forty feet depth. He noted his observation as point A. Then he observed the color at hundred feet depth. He noted his observation as point B. Then he observed the color at four thousand feet depth. He noted that observation as point C. He now have some ideas how the color of water changes according to its depth. Would the color be darker or lighter at point A than at point B?

A:
lighter
