With respect. Your analysis that "it sits on the fence" is entirely incorrect.
Mamil is saying that black is the same as high vis/colours. He is saying there is NO difference.
The studies where relevant all debate the amount of the difference.
so for example, the first conclusion:
Fluorescent/reflective clothing such as a ‘high-vis’ jacket is not very good at increasing a cyclists' visibility/conspicuity to drivers, in particular after dark [Wood et al 2010, Rogé et al 2019].
That is still a win for high-vis being better than black.
This is such an easy argument to win, since the question is:"is it easier to see colour than black?".
Next up, do square pegs fit into round holes?
fair enough. this could be a totally separate point that I'm pretty sure I never disputed the nuances of since we got stuck on the binary question.
