If I put identical red and violet(or blue)objects in the sun and measure their 
surface temperature, the violet one is always hotter.  But the color we see is 
the color that is reflected, and violet has more energy than red.  So if violet 
objects are reflecting more energy (thus absorbing less) why aren't they cooler 
rather than hotter (and vice versa with red objects)?   Erik
