Screen Colour

Hey, in class my teacher said that screensavers should be black so that they use less power.
Does this mean that having a black wallpaper for the desktop would also use less power?

You save memory by using fewer colors in your ss & wp.

How so, you still need to load the pixel value into memory so you'll still need resolution.width x resolution.height x color depth memory to store it

What I meant was that the wallpaper file sits in the memory, so a less complex picture leaves a smaller memory footprint.

i once read a great joke statement online that said that the American national power grid had given issued intructions for all web designers to cut power consumption by posting darker pictures on there web sites. The rational being that in binary darker pictures tend to use more 0's than 1's, and 0's use less power than 1's.

total bollocks, but very funny non the less.

Is it true that the color black uses the least power, and the darker the black, the less power it uses?

No, stuff displayed is stuff displayed. The "darker" an image is, the "colder" it will look. This is especially true in artwork. The intensity of colors has no effect on heat dissapation because video chip and monitor display what they are instructed to display. The same amount of electricity is used. So, not a difference.
