It would be really good if we could paint blocks that are placed in the world, by pressing p on them with a paint item or something. At the very least, I wish that we could color each tier of armor just with paint, so that I don't have to make a certain color of basic hull, then add some colored materials to make it into standard armor, then potentially repeat that if I want advanced armor. It is a pain to have to get a certain color of minerals to make the hull colors I want, and it makes no sense. After all, if someone wants to build a house of a certain color, they don't go all over the world to find a tree that is the right color, they use whatever good building wood is handy and paint it the right color.
