I'm not entirely sure I agree with how this is making it's point. Maybe people are bad at remembering specific hues but I would be curious how accurate people are at using the 3 sliders to match side by side colors and how long that takes. Personally I spent so long trying to figure out how to do a specific greenish-brown that I wasn't entirely sure if I was still trying to match the original color or if I was just comparing colors to what I just saw
Plus context changes a lot, they start you on a black screen and then show you the color. However the game seems to hit shuffle on the sliders when you go to guess giving you radically different context
It feels like this is set up to reinforce a point not make a new argument
