I'd bet it becomes even less visible. I find black mosquitoes almost impossible to see without a contrasting background. I can't imagine how you'd see them if they were moving in a circular motion at 25 rpm. Humans are remarkably bad at telling if something is 50 or even 75% dimmer. If this were spinning at 25 rpm you'd be dealing with something 4% dimmer if it was non-emissive. Whereas if it's white you see an actual change in color, which humans are really good at.
