Really?! Sheesh now I'm going to have to pop into UAE and try it, hang on...
Ok, it worked! Just open a shell window and press
ESC, then [42m and press enter. It'll say unknown command, but it does change the colour, sort of.. but it only changes the background of the text, not the whole window.
I think I have shellcolor on a CD here somewhere, I'll see if I can find it.
