Should I contemplate a man's choice in nail polish?

So when i look at people I can pretty much tell if they are freaks. long hair, obese, t shirt that says "Good vibes". and hand that have nail polish on them. I told this thing "You nail polish looks good on you". I think it was a a little embarrassed. I call it a thing because I don't know what it might identify as. I don't know if it was a woman or man so i call it a thing.

Should I contemplate a man's choice in nail polish?
