Not sure about 94 but around 95/96 yellow was an option. I bought a frameset from new and days earlier had seen a team rider at the London bike show on a yellow ali framed bike. I asked if it was possible to get a P7 in that colour and a few days later it was duly delivered.
So I've just picked this up from the sandblasters and I'm still no closer to deciding what colour to paint it. I'll be getting it powder coated so fades aren't really an option. At the moment I'm leaning towards Satin Black but that's a bit boring
