A fellow by the name of Jon Doucette took this idea and created a low wattage web palette that, according to article, only uses three or four watts more than a completely black screen. Starting with the EnergyStar wattage ratings, he came up with six colors that work well together. White is included in the palette but is it supposed to be used as an accent color. The savings do not apply to devices that have a constant backlight, such as LCD monitors, but it's a neat idea that is especially practical for handheld device and large web sites. Save your watts!
