What Others have Done.

Page 3, there is a procedure.
Basically, this study does what I wasn't so sure about. They sat people in front of computors (in separate office cubicles) and had them look at colors.

Questions they asked-
What emotional response do you associate with this color?
How does the color make you feel ?
And, why do you feel that way?

I guess I can't say they are wrong, but I've been thinking more on a larger scale I guess. I don't think it covers enough.
I'm confused with how they categorize it.

NOTE-- This is basically what I did in seventh grade for science. It didn't work so well.
