15% of all males are colourblind. I wouldn't call that remote.

In fact, anyone who gives a presentation should check that their slides are actually understandable by someone who's colourblind. Else they are going to fail to get their point across to a significant part of their audience.

(That reminds me of one scene in the movie "The Abyss", where a diver has to disarm a bomb by cutting the black/yellow wire, not the blue/white one. Unfortunately, his source of white light broke earlier, and his only remaining light source emits yellow light ...)
