edit: sorry, I didn't see 70sSanO post above. Regardless...

Check out the Columbus carbon fiber forks. They are very nice quality, good looking, all carbon, light weight, flat black, fairly low key logo-ing. Plus, they're Italian so wouldn't be a travesty on a Colnago! If they have one that suits you, I don't think the aesthetics would suffer too much. 8-)

I have a Minimal which is a great fork and I'm very happy with it. There's a bunch of varieties for various types of head tube and brake set ups. I'll bet you can fix your faux pas for in the reasonable vicinity $300US if you shop around. I bought mine from Chain Reaction for quite a bit less than that a couple of years ago. Then sell the Colnago to a tiny frame owner?
