More Ores (Sapphire, Red Beryl, Goshenite, Enderite, and Aquamarine are ones I thought of), More Chests (Nether Chests, Dyed Chests, and Chests of differing Wood Variants), Technicolor Slime Blocks (e.g. Red, Orange, Yellow, Cyan, Blue, Indigo, Violet, Magenta, Pink, Rose, Brown, White, Gray, and Black), and more Wool/dye colors (There are no Indigo, Rose, and Periwinkle Wool Colors and having Rainbow Wool from Minecraft Earth would be nice), with the carpet variants.
