Natural Paint

Using Dyes players should be able to make paint.

Every time the player wants to make paint any dye must be placed into a pot for a small amount of paint or a cauldron for a large amount of paint. (Current flower pot before 1.17) 

When the player has placed the dye into the pot or cauldron it then must be mixed with a bucket of water. Once the water is added the paint is ready!

The natural paint changes the condition of any block however the best blocks to paint are concrete blocks, concrete powder, terracotta, and wool. With this being said the best color to paint on is white because it doesn't affect the color of the paint. Let's say you paint a blue concrete block with yellow it will turn green! or a red concrete block with white it would make pink! (If you only add one layer of white.)

What also makes paint special is that one side of any block will be colored while the rest of the block stays to its original colors. This means players don't have to double up walls where one room is White while the other room is gray.

edit* for applying paint you will need a paintbrush. A paintbrush is made of 2 feathers and 1 stick. The durability will be around the durability of iron tools.

Overall, I think paint could be a really good addition to Minecraft!
