Brian, I noticed that also. I believe the reason only the bottom of his feet are blue is exactly what you said. The rest of the scene is not blue because the blue reflection from the water is not strong enough to affect the overall scene. The blue is overpowered by sunlight. The bottom of his feet are close to the water surface and acquire that color. And they are also partly in shadow of the top of his feet. So I think anyway.

Oh, and near the bottom of the Wikipedia article is a reference to a paper that suggests that about 50% of adults think Plato was right. Hmm.
