The rest of my kit is mostly black running shorts or tights, and tops in various colours - black, orange, green, read, blue, fluro yellow... All from women's ranges, so I've never felt constrained to pink.
Maybe it depends what ranges you buy from; mine tend to be Nike or Adidas but, as it happens, my one pink top is New Balance.
I often run very late, for the same kind of reasons as you Nell3 - Quite common for me to run in the evenings at 9.30 or so.
And next week I'll be in America with work... 'tummy troubles' (if you know what I mean), make it difficult to run early morning before my meetings; then in the evenings I'll have to go and eat with colleagues, meaning I can't get my run in early in the evening as I'd prefer... so I expect to be running at 10pm or later. My body clock will be all over the place!
