Psychology Of Color: "Color is a meaningful constant for sighted people and it's a powerful psychological tool. By using color psychology, you can send a positive or negative message, encourage sales, calm a crowd, or make an athlete pump iron harder.
Employ the latest color psychology in all facets of marketing and particularly in logo design, web site design, the cover of a book, or the package of a product.
The field of industrial psychology has a sub-field that studies only the psychology of color. It is no accident that Campbell's soup has used the same four colors on their labels for years and years. When I mentioned that product, I'll bet an image of that label popped into your head."
