I've done quite a bit of research on colors and their effects on sales and psychology and what not.
Other than going into a longwinded thesis on everything I've read, the common thread seems to be this...
Warmer colors tend to evoke action and response. Warm colors being in the yellow and red spectrum.
Cooler colors tend to instill a calmness and inaction. Cool colors being those in the blue and green spectrum.
Lighter colors in either spectrum also have an active effect while darker colors subdue.
On the flipside red can tend to aggitate and aggravate, and blues can tend to bore.
Lighter colors in either spectrum also tend to be a call to action and darker colors in either spectrum has an opposite effect.
Yellow attracts the most attention. Black and white are the most professional. And royal blues seem to inspire confidence.
