Tagged Concrete
The material has a base set of inputs for the concrete or wall textures.
There are three layers for the tags. The tag textures can be swapped out. Each tag is stored on one of the red, green, or blue channels so that their color can be controlled individually.
A material for a side project I have starting working on.
It is all contained in one material at the moment.
The base concrete was created in Substance Designer, special thanks to the "Get Lernt" youtube channel for the tutorial.

The material works well in a small area, but not so much across a larger wall surface, so the next step for me will be adapting it to tile better.
