3. While helping my coworker decide on the paint for his new co-op, we came across a web-site talking about experiments in the emotional/behavioral effects of different colors. The experiment seemed fairly conclusive in the "different colors certainly have different effects" camp, but then ended with the statement that the effects were the same on a group of blind children as they were on the sighted subjects. This, of course, led us to conclude that the whole endeavor was bullshit, but it got me thinking, in what subtle ways might non-optic nerves be capable of sensing light?
