I like your first thought, Alma! :P and the second one is kind of close!
The first thought that comes to my mind is a person who does not pay much attention to the skin color of another person.
The second is a person who has different vision for the colors green, blue and red than most other people.
Not using the literal meaning of the world, i would think that someone has no taste in the color of the clothes they are wearing hehehe
LOL!!! hehehe, You think that these are the only colors a colorblind person can see??
shades of grey and green and red
