What color is the sky in your world?

This was always my obnoxious little phrase to use when someone was doing or saying something crazy. But at one point I started to think... is blue the same for everyone?

When I look out of my eyes, I see certain colors. For instance, I might be reading a book at tell my son, "this is a red ball". But is the color he sees as red the same color I see as red? Or does his red, perhaps, look like my green? Do everyone's eyes process color the same way? I figure this is one of those things we would never really know, because every time I see "my red" I say "that's red!" But maybe every time my son sees "my green" he says "that's red!", because it's HIS red.

This has become my explanation for mismatched outfits. Perhaps colors look different to the person who things orange and purple look good together. And I have always questioned why everyone thinks red and purple match. Perhaps MY red and purple don't match, but someone else's red and purple do match.

It's way too early on a Monday morning for this kind of analysis, so I will blog again later.
