I've often described colour blindness as an optical illusion, and that confetti illusion is exactly what I have in mind. Peanut better has a green lid and green label which makes the slightly ambiguous brown look green. Or the walk symbol at a cross walk - usually a light is white so I just assume that walk symbol is also white (even though I now know it's green). Or the statue of liberty - it's a big rock so I assume grey, even though I know it's green. However when any of these are looked at in isolation, it's clear what their correct colours are.

So, the statue of liberty isn't made of rock, it's made of Bronze, the Copper oxidised (amongst other things) eventually leaving it a bluey-green: https://www.iflscience.com/chemistry/the-true-color-of-the-s...
Depending on the lighted walk symbol, it may be white. I think most in the US are but some localities vary.
