I believe I'm Red & Green deficient.
Traffic lights "Green" looks white to me, purple usually looks blue to me, I confuse Yellow/Green a lot, Gray/Pink, etc.
I see all the same colors I normally see in day to day life, but I still have no clue what I'm looking at. I've seen "greens" and "yellows" based on what people say are green and yellow, but in my visions I still have no clue which one it is.
And I can't ask anyone either
I can still SEE those colors, I'm just deficient, so they probably aren't as vibrant or noticeable. I believe what's actually happening for something like purple for instance, is there isn't enough Red for my eyes to pick up on, so only the blue is noticed. Whereas Maroon, I can clearly see the red in.
However if there were the same amount of red on a white background (therefore being Pink), it would probably look gray to me.
Give me the Hexadecimal notation though and I can tell you what color something is
