I recall reading a paper on a study done by the National Research Council of Canada, who were doing quite a lot of hi-fi basic research at one point. They took two identical 2-way speakers - made identically and also tested to measure within 0.5 dB of each other at any frequency 20-20,000 Hz- and played them for an audience of testers. One speaker's cabinet was painted red, the other was blue.
To a high degree of statistical confidence, listeners reported that the red speaker sound warmer, more emotional. The blue one was neutral, analytical.
My speakers are white, and I can change their sound by wearing colored glasses.
White is cool, but I prefer my speakers invisible if possible. Black seems to be the closest.
