What I meant was that if you would try to paste the icons into buildings-large/small.pcx the only colors that would be OK was index 254 and 255 (the border and transparent ones). The others are different from the original Firaxis, meaning the icons have to be pasted into a RGB-version (un-indexed) of buildings-large/small.pcx and then re-indexed the whole file to make it look right. Just looking at them as a single image file won't be a problem, but since they are meant to be included in the buildings-xxxx.pcx file, it would have been better if they already had identical colormap (or palette if you like) as the Firaxis origin. I'm not unhappy with the work you've done, BTW. Just mentioned it for ease of implementation in people's icon-files, thats all.
