Oh god please dont judge
NOTE: This is not the promised paint mode. It is just "vertex painting" (a more pixellated form of painting). Just a way for beta testers to play around with colors.
* The colors do so far not save.
* The colors do not yet transfer to the sculpting phase.
* The colors do not yet undo properly
But it brings in some new aspects. Be sure to test out the "splash" color.
