It occurred to me after recalling cooling problems in the layers near the bed that many popular build surfaces (e.g. BuildTak clones) are black, which should radiate the most heat - onto the part being printed, which is generally undesirable. Is there a reason for this? Are there (white) build surfaces designed to minimize radiation of heat that might help avoid cooling problems in the initial layers?

I believe that the color is just a design choice, and doesn't have that big of an effect on the print itself. Changing the color wouldn't have an effect on the print itself. If you are looking for a solution to minimize radiation of heat going up to the build, you could either lower the heat of the bed, or you could go into the advanced print settings and change the bed temp after the first couple layers.
