Three former SpaceX supervisors told Reuters that Musk would have machinery painted in industrial safety yellow repainted to black or blue because of he didn’t like how it looked. The ex-supervisors also said that some workers were told not to wear yellow safety vests when Musk was on site.

It says they couldn’t wear yellow safety vests, but I’m guessing, at least at first, that they didn’t have two colors of safety vest available for all employees.

And repainting machines unsafe colors because you don’t like yellow?

Just criminal assholeishness. If he wasn’t so rich, he would be charged with reckless endangerment.
