I had a pink ME ultra fleece jacket in the early 80's. I think they claimed it was magenta. It was half price, at £16, and groovy out on the hills in fog.
But for bikes I like bikes in neutral colours so I can change the colour scheme now and again via the brake cable and bar tape colours, Pink is a bit too primary for that. Quite happy riding one though. Couldn't care less about colour, if it's a borrowed one or hired.
