If you've got a B&W darkroom, you've got most of what you need to print color. I mention this because people often think that making color prints requires lots of exotic stuff, but it doesn't. Extra stuff you'll need would be color filters, color chemicals (RA-4 developer and blix), and of course color paper. You won't need the filters if you've got an enlarger with a color head. Some people add extra stuff, like print drums (but you can use trays), a color analyzer, etc.
That said, the learning curve for color is such that you'll waste a lot of time and paper if all you want is a couple of prints. If you think you might want to do more color prints in the future, though, you might look into doing it yourself.
