Black was the center of two disputes about its eco-friendliness. In one black was perhaps good; in the other, bad. You can be the color judge.

Good Black

The first case was Google’s "Blackle" - an alternative to Google's white page - that would save 3000MWh per year. Others claimed that "While it may be true that a CRT monitor uses 15 watts less with the black screen, only 25% of the world's monitors are CRT." Some others put this to a test of 27 monitors ("The Final Test") and found that LCD monitors with a size 22-inches or less, all showed an increase in power consumption using Blackle. Beyond the 22-inch mark however, five of the six models showed a fractional decrease in power consumption when using Blackle.
