Need help with custom sleeved cables

I need to know where you can buy custom colored sleeves for a build (obviously). If you have to do it yourself, then I'm out on that.

(Sorry if this is in the wrong section!) 

Here's an OCN thread listing some places to buy paracord:

If you don't want to do it yourself Bitfenix has some extension cables that come presleeved, there may be a few other presleeved options out there, but doing it you self with either para-cord or the plastic sleeving because you can get what ever color, or colors you want instead of predetermined.
