Drivers won’t see it purely because they’re so used to seeing it. One of the girls I used to work with has a bright neon pink jacket and you could spot her very easily because the colour is so unusual.
Combine your coloured clothing with lights and contrasts. The girl who wears that pink jacket every day does that and has never once come into the office complaining that somebody’s pulled out on her on her ride into work. It might be a bit garish, but it does the job.
Don’t do this
Get hung up on wearing pink. Bright orange also works well. As does just about any bright colour that contrasts with your regular riding kit.
