I've been looking at the skycolors files, and although there are definitely some changes that have been made (a comparison of the files made with a hex editor shows differences between the modded files and the originals), I'm finding it hard to see any real perceptible difference in terms of colour or shade (the files contain only two *.tga files, so they are graphical in nature). Their size has not changed either, so I'm a bit stumped as to where the changes lie, or what the changes do.
