Show HN: A color challenge that will break your faith in your eyes

#1

Post by MinZhou »

It looks easy: a grid of identical colors, except for one that’s just slightly different. At first you’ll spot it instantly. Then the differences shrink, the grid grows, and you start doubting your monitor, your eyes, and yourself.

Curious to know how far you get before you can’t see it anymore.

I tried using various settings on my Samsung phone and they had a serious impact! Adaptive = level 32 AMOLED Photo = level 16 Basic = level 39, maybe 38, can't remember now.

Pro-level!

That level is hard! I find myself sweeping my eyes over the grid, looking away, then back a few times before I can see it.

App said I was in the 5 percent. Lol, the 4 color vision people must rule the roost! Us standard RGB types can throw a few solid punches...

Agreed with other commenter: green is killer.

Is that true for all displays you have used?

Purple is harder when I use the AMOLED cinema and photo options on my phone.

I want to try this on a CRT, Plasma, LCD.

I have all these. Be right back!
