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?

    $\begingroup$ I suspect the difference would be negligible, but now I want a white one, just because it would be easier to see the print for most colors (except white, obviously) $\endgroup$ – Joel Coehoorn Apr 8 at 1:32
