Have some answers from nine years ago -- presume still accurate but we'll know if it isn't! <g>

ZA-Probably would - hmmmm, I *like* fried vegies...but maybe not! ZA-The idea of white wallboard is a good one, though - thanks!
In order of reflectivity, titanium white, flat, is the most reflective, followed by glossy, followed by a number of colors, with the least reflection created by glossy metallic colors such as silver (glossy silver paint only reflects less than 80% of the light which strikes it).
This is kind of nice, since titanium white is about the cheapest paint you can get. And you are right - during the heat of the summer, you can put too much light/heat on plants.
