I recently bought a SCREAMING orange top for running, and yes it screams, just like your pink. (They call the color Cherry Tomato apparently, but it really is a bright safety orange.) When I took it into the changing room to try it on, the orange that stood out so brightly on the rack on the shop floor, almost disappeared in the low light. For comparison I grabbed a true hi-viz yellow Brooks top and brought into the changing room. Unlike the orange, the yellow stayed lit up.

I have one of those Brooks tops already, and I don't like the fabric well enough to buy a second one, so I bought the orange. But I wear the orange one only in bright sunlight. If it's full dark, then reflective matters more than color obviously. If it's cloudy or toward evening, it's yellow and only yellow for me.
I agree with you on the yellow. My husband, Mr. Engineer, insists that the hi-viz hunter orange is the best color for dusk...he said it's proven that people can see it, why else would they use it for hunters since hunters are usually out at dusk, yadda yadda. I found a chart that said that the lime yellow color is actually the best: http://www.ndt-ed.org/EducationResou...htresponse.htm and still, DH argues with me. That lime green/yellow is right in the sweet spot for the human eye, around 550 nanometers, so we see it the best.
