I (20F) noticed this summer I have a hard time distinguishing different shades of the same color. I worked a job where we would inspect dorm rooms, and when I’d look at our maroon mattresses, I couldn’t really tell when they were dirty because I could notice the typical darker staining my coworkers would see. My coworkers would come to the room and get into me saying it was obvious it had to be replaced- but I had no idea.

Could this be a kind of color blindness or just normal?
