My short answer to the opening question is "Yes".
Once upon a time I ordered a custom frame from Mercian Cycles. Faced with a near infinite choice of colours, I soon realised that if I'm buying my perfect frame, it will look fantastic in
any colour.
Predictably enough, when it arrived I wasn't particularly happy with my choice. Far too conservative in retrospect. So if it had been a case of "you can have any colour as long as it's lilacky-clay", I'd probably have ended up with a better result.
I had a nostalgic look at the Mercian site - link below.
If you scroll down to the pictures of actual frames, do you see anything that wouldn't be absolutely magnificent?
