Very interesting. I would have loved to have a colorblind trait. My sister is colorblind and I never understand what she is seeing when she describes her favorite color as a color I know she can't see. She loves purple, but she sees gray or blue. So if she could ever see color, would she actually like purple? I don't know.
I honestly love seeing the world through my sims eyes. I love when sim kids talk to their imaginary friends and only they can see them. I love how in TS4 they see special effects when playing with toys that no one else can see. So yeah, I would have loved something like this just because it would have made the sim more endearing and unique in the world.
