I'm a CS guy who was completely forgotten red-black trees after about 5 years in the real world.

At least you had red-black trees. When I went to school, we didn't have any red, and we were lucky to get black. (Seriously, though I could guess it had something to do with binary trees, the name 'red-black' wasn't made up until a couple of years before my Data Structures class, so the name probably didn't make it into the book we used, though I don't have the book anymore so I can't check).
