Wood stains.

As you know dyes can be crafted from flowers, cacti and a few other things. Dyes are used to change the color of things like wool, concrete, and collars but, to take the design of a bamboo door and stain it purple and pair it with stained planks, stripped wood, fences an even torches would make the ultimate base. Chests, boats, and even live trees and leaves could all be stained into a new kind of biome where every block is the same or mixed colors. Some would go as far as an entire world the same color or multiple colored biomes. Rainbow beaches are already a thing and so is coloring most blocks so why not wood to make minecraft even more in depth.
