For those who want to test their perception of colour, I made a little game called "What's My JND"

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

Also in case you're curious, over 2 million people have now played this game 🥵

Site traffic is up quite a bit.

In celebration of 2MM I made a "Hard Mode" alternative version, idea courtesey @jaffathecake

Hard mode: find the odd square out of nine. No gradient hints, just raw colour perception.
