As the title says I think the game really needs some blue blocks for chiseling paintings and murals and whatnot. I LOVE chiseling in the game because I just find it so relaxing, and do it in vanilla (with some help from a chisel tools mod) and only use blocks that are obtainable in survival. So far the only blue-ish blocks I have to use are andesite rock which is a blue-grey colour, and glacier ice which just doesn't work as well as I want it to
Maybe we could use mash for chiseling too since the different mash types have nice vibrant colours, or there could be some blue ocean rocks that you can find or something? I dunno, I get this is so specific but I wanna keep on chiselinggggg!!!
