One of the very minor complaints I had with the BG series was how the spell Stoneskin changed not only the skin tone, but also that of the clothing. I guess some players liked the pronounced visual feedback of restored color once the skins wore off, even though there was a status icon. But it is a long duration spell which the AI would auto-cast immediately, and I never liked losing my colors when shopping or otherwise not in battle. I want to look good all the time, ya know? Besides that, stoneclothes just don't breathe as well.
