You will find one if you look.

Or, you can track down a color head for your enlarger.

Or, you can purchase yellow and magenta CC filters and stack them in your filter drawer. You get 5-point precision that way, while with a color head you get 1-point precision. If you want to go this route, look for the small Ilfochrome set on E-Bay (or trim down a large set). I have one I would gladly sell you for very little, but it is kind of a "permanent loan", so I can't. They should be cheap on E-Bay, however.
