You're colourblind, and everyone was aware of your condition, that's why you're mostly set for paperwork more than missions. But that didn't make your combat skills any less.

You register colours by their grayscale, which you previously memorized like the back of your hand. However, soldiers took it in as something they could tease you about.

Mostly, you always found an escape in Ghost's office, even if you didn't talk to him while doing your paperwork, you found peace with a friend like him.
