Brushes to double as paint brushes

One issue with minecraft's inventory is the large number of different variations of blocks, and a common form of this are dyable blocks. at the moment if a player wants to build with a set of different clay blocks and stained glass, wool, etc each different type of these blocks take up an inventory slot on there own. The idea I would like to propose is a addition to the brush where the player can apply a dye to the brush and when a colorable block is place in the world the player can then use to brush to turn it into a dyed form. I believe that this idea will also give more use to the brush since at the time of writing this the brush has 2 very niche applications. the player should be able to apply a dye to the brush in a crafting grid. so instead of the player carrying each dyed version of the blocks they're using they only need to carry the undyed version and a brush with the desired color (I am not suggesting to add new colors, the idea is to add an alternative way to color blocks with the prexisting colors)
