I'm still not convinced the white and gold people aren't just trolling.

I want to know what some tetrachromacic people see.

Since the monitors themselves are RGB, I don't think tetrachomats will see anything different.

I was seeing white and gold this morning. Read the reddit post, somebody had done a contrast adjustment showing the black/dark brown and blue and when I saw that, front that point onward I only see blue/brown (still don't see the black, it's a dark brown to me).

The funny thing is, this morning when I first "got it", the blue was very light, and I've been looking at the original tumbler throughout the day and I swear it's getting darker blue every time.

Now I can't even see the white and it's kind of blowing my mind. I remember the WTF moment when people said it was blue/black and only seeing white/gold, but I just can't reverse it and see it again.

I see the blue when I adjust the scale, but can still make out some gold at the top.

right, there's no lighting scenario in which black fabric looks gold.
