It's not an issue with red colors in general. It's an issue of small low contrast areas of red and yellow (yellow being green + red). Go frame by frame in the vid of the body and you will see frames that look more like black with a white stripe, albeit to a lesser degree.

Also it is worth thinking rationally and asking yourself if it makes any amount of sense that any entity would go to the trouble of staging such an event and then say "meh don't worry about the shoes they look close enough".
