Hardly anything edible is blue. Many tasty things are red or yellow; much of the rest of the terrestrial living world is green.

Our eyes are very poor at spatial location of blue things, to the extent that the old NTSA television standard just kinda slopped some blue somewhere in the neighborhood of things that were supposed to appear blue, and our eyes accepted it.


OK, I need some help on this one; I heard this the-sky-is-not-blue idea on NPR before seeing it here. How is the sky not blue? Not trying to be simplistic, but it looks blue to me. If it isn't blue, what is it? And if we perceive it as blue, doesn't that make it blue?
