Colorblindness now prevents you from seeing wire colors (#91315)

Being colorblind now makes you see all wires in tones of grey.

Also fixes the eyechart not taking the monochromacy quirk into account
when checking for colorblindness

Makes the quirk/trauma a bit more immersive and can lead to funny
situations when you know which color to cut but can't find it.
