Saw that colored chalk was back IN!
Years ago I experimented with using food coloring to color chalk--it worked great. It just takes a few drops on a block of chalk (doesn't work that well with powdered chalk, though), and with experimentation you can get any color possible with a combination of the primary colors.
I thought about once putting together a kit which would consist of a color card that you could match up to the rock and be correlated to a mixture of x drops yellow, x drops red, x drops blue. Then just crumble the block and there you have it. But it seemed like a lot of work at the time.
It would be nice for someone to come up with a color card for use with food coloring. Let me know if that happens, I'd like to have one.

I think Mal Daly shared this tactic in another colored chalk thread. Perhaps it's a good way around the slick feel of the finely ground commercial colored chalk, but I think you might still have to confront the "stains the rock" problem.
