Shook off the funk today by getting out shopping at Trader Joe's and Barnes and Noble. Having dinner comprised of lots of little frozen doodads from TJs (tacquitos, vegetable samosas, dumplings, etc.) it dawned on me that we've never bought a single food item there that wasn't delicious. They have the freshest-tasting salsa of any grocery I've

I *think* it's due to the angle of the sun required to make the rainbow. To see a rainbow, the sun has to be behind you, and the center of the arc of the rainbow is directly opposite the location of the sun. So that makes me think the area inside the arc is receiving more direct light than the area outside it, hence it's brighter. If the rainbow weren't there to make a line, you probably wouldn't notice the gradient. (but this is a guess, it might be some other effect of the angle of the sunlight, or an illusion; I really ought to actually know this sort of thing)

Alternatively, my first thought was that it could be an optical illusion caused by the different colors framing the region - the same shade of blue looks brighter next to the violet edge than it does next to the red edge of the rainbow.

There's nothing better then a big rainbow, or a beautiful sunset.
