I've seen that every natural block can't be painted (except natural blocks that can be crafted) Now, that's notr so good as it limits creativity. Also decoration can be painted, this includes lights, i'd really like to paint my violium lights red soy they fit well in my avian base. Also there could be more blocks that give light or a red bioluminiscent block, or just paint those blocks! in summmary. Paint every possible block (even the ship?)
