There aren't many entries in the jam that are in color. The use of it here is great, really helps readability in something that could've been a mess without it!
The module's actual usability or balance, to me, is secondary to its novelty. This is probably something that'd have to be a central gimmick of a campaign or oneshot--maybe turning a run of Mandelbrot Set into even more of a roguelike or something. I think it's worth your time just to see that someone even made something like it and actually executed on it in full.
