There are so many phycological reasons for things; like the way the layout of a store is, and why they change it every few years. Why certain items are placed at the entrances, why the electronics and toys are in the back, why jewelry is placed next to the women's clothes area, why malls are designed to try and make you lost... and that's just grocery stores, malls, and wal-mart.
I wonder what came first; the association between red and gold, and hunger, or the prominent use of those colors in food advertising.
This could be tested by running the "which colors are associated with hunger" test on a population who has never been introduced to any marketing that uses those colors, but finding those kinds of people must be pretty difficult at this point.
