High vis colors are fluorescent in sunlight but do nothing in the dark. Lots of reflective stuff. Yes even the dorky ones on the pedals and wheels. Marathons and probably some other similar commuter tires have a reflective stripe on the sidewall. Reflective clothes and bags too. You can imagine a backpack blocking your reflective clothes. The ones that have reflective piping are more of a feel-good than effective.
Keep warm - maybe not this month in this hemisphere in this year!
Tangent about colors.
Did you know the F117 was originally supposed to be painted in a camouflage pattern of pastels? Because those wavelengths disappear faster in low light and would have been better than black in regards to contrast against cloud cover.
But real men don’t fly pink airplanes. So it was painted black.
