8: Brock is Colour Blind
Colour blindness affects 1 in every 12 men, and The Beast is one of them. However, when you take into account that most of the deadly predators in the animal kingdom don’t conceive the full-colour spectrum either, it kind of makes sense.
Most people affected by colour blindness are able to see things as clearly as others but they are unable to ‘see’ red, green or blue light fully. Brock has the most common form of colour blindness, red/green colour blindness, which means he tends to mix up colours which have green or red as part of the whole colour.
