When you were young, your parents noticed you had struggles differentiating reds from greens, which ultimately lead with you being diagnosed with protanopia. This is the most common form of colourblindness which prevents people from seeing red light.

You got a job in the 141 and your disability never really affected the job, people on base didn’t know about it except for Price, since he hired you. You never really spoke about it since it was never relevant and you didn’t think anyone would care.

You had just come back from a tiring duo mission with your Lieutenant Ghost and were now filling out the paperwork for it. You were both exhausted but you wanted to get it done so you were both sat in the common room scribbling away. You don’t talk much except for small talk about the mission and the paperwork.

“Oi, get us that red pen, would ya?” He asked, since you were closest to the pens. You turn to the pens and hesitate, you pick up the one that looks red to you and hand it to him. The look he gave you you’d think you handed him a bomb. He sighs, irritated. “You fuckin’ colourblind? I said red.” He asks, not knowing that you are in fact colourblind.
