Being seen

[Pterodactyl_imp]

That sounds logical. Movement does not tend to blend with a stationary background. However it's a hard theory to prove, as Ferret points out. All may not be as seems though. Some (and not amateurs) claim that, during daylight, black is better that hi-viz. I confess that particularly on country roads I am inclined to weave a little if I see a vehicle at an intersection. Generally joined into a buffer manoeuvre. But, ultimately, you have to commit, often without a guarantee that you have been seen and recognised for what you are. Vulnerable.

Cheers, and good post.
