Simply put color dyes to color buildings and some liftable things. I saw a thread on someone wanting labels for barrels and such and it reminded me of wurm on how we would dye barrels different colors for sorting purposes. So, ideally you would use some water with another item (lets say clover) and mix them together to make a green dye. This would go under the potions in your crafting. Quality of the dye would effect how potent the color is: low ql light green dye, high ql = darker more solid green dye. Now, that you have your dye, you can use it to dye things such as barrels, crates, baskets, houses, boats, wagons, cupboards, things like that... This way you can sort things with colors and can easily see what crates have what once organized. Also, it's just fun to make your place a bit unique by dying your house your fav color

even be able to tell your boat from your friends boat while out adventuring. Obviously though, bigger things would take more dye then smaller things but all in all I think its a neat idea that people might enjoy.
