Hi. Please play this amazing JND color game my friend Keith made and see how good you/your displays are at differentiating between similar colors. https://www.keithcirkel.co.uk/whats-my-jnd/?r=filmgirl
What's My JND?

Find your Just Noticeable Difference in colour perception. How small a colour difference can you actually see?

@film_girl I forget my score, but apparently it was incredibly... average. I'm OK with that.
@xgranade I worked very hard to get the high score I got last night and my eyes hurt after as a result so average is prob smarter, all things considered!
