Consider a less cluttered way designating which tile belongs to which codemaster

[banool]

I feel like the 4 triangles on each tile end up making the board a little cluttered and hard to read, I'd love a better way to do this.

As for why I'm using the corners in the first place: With words you can highlight the word (for the codemasters to know what is what) and the tile (for the codemasters and players to know what has been selected, but with images you only have highlighting, so I had to make my own little images with the coloured corners.
