Speaking for the colorblind folding contingent, I can say that while this sounds like a great idea, in reality, it would not be helpful.

I have only a moderate case of protanomaly (red-weak color vision) and deuteranomaly (green-weak color vision). On a monitor, however, I can distinguish only a handful of colors: white, black, grey, blue, and red... which happen to be the five colors used here in colorblind display mode. I could also use yellow or green, but not both, since on the monitor those two colors look exactly alike to me.

So I have the ability to use only four, maybe five colors (black on black doesn't work real well) to distinguish some dozen functions on the undo graph. Even if I could choose the colors I wanted, I don't have enough viable choices to get the job done; and I don't have good enough color vision to distinguish different shades of the same color, either. And so, I ignore the undo graph, except to return to a specific peak or trough.

I`m not colourblind, but we should have more options for players who need it.
