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 Tried again and got 0.0026. Put my brightness at max to do that. 250 nits. 6-bit screen.
