i've read around a little about energy consumption, screens and colour.

contrary to my superstitions it looks like LCD's shouldn't actually be 
considered in the equation after all. this really only applies to CRT 
displays. 

LCD's have a back-light that is continuously on. a 'black' pixel is
merely just a crystal turned such that it blocks light from the
backlight. for this reason it should make no difference whether a pixel
is black or white. 

some people are reporting small reductions in power useage on LCD 
displays but most notice no change.

i thought that there might be some sort of load calibration done as a 
result of whether a crystal blocks light or let's it through but apparently
that is a design for LCD's not yet in the market. 

to summarise:

  if you're using a CRT you shouldn't be. 

  LCD users can dress in white.
