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

https://www.keithcirkel.co.uk/whats-my-jnd/?r=ARUjKP__-ve-

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

What's My JND? Hard Mode

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

Okay, clearly y'all love colour games, so with millions of plays on jnd & jnd-hard thought I'd dust off and polish up the _original concept_. Hue shift:

Drag one colour to match the other, 10 seconds to do it. You know the drill. Make me proud gang.

Hue Shift

A chaotic colour-matching game. Drag to shift hue and lightness to match the target. 10 rounds. The clock is ticking.

@keithamus @jaffathecake Found the text overlay near the bottom a little distracting, TBH. Maybe have it fade out after a few seconds? Or live somewhere off-grid? 🤷‍♂️

@keithamus Somehow did a lot better than Easy mode, with third place (for now)! Maybe cleaning my phone did help…And congrats on 2M players, I love this stuff (and my coworkers too!).

(correction: no I didn't. Got 0.0070 on easy mode.)

I have a feeling that I'm better at certain colours than others (or maybe my monitor is). That might be an interesting variant: are you good at seeing differences between reds and not greens or something...

@sil @jaffathecake anecdotally a lot of people say they struggle with reds/pinks or blues, and I suspect it’s chromosomal (based on my own anecdotal observations)

@keithamus @sil @jaffathecake Red green colourblind is by far the most common type in guys; and it’s a spectrum not a binary. This lines up.

(Spoken as a guy who is red green colour blind; yes I can see red and green. No they are not opposites to me; they basically don’t contrast against each other. I get oranges and browns and pinks “missing”. Autumn is boring monochrome unless you zoom into each item. Berries on holly bushes are invisible until up close. Then they’re red.)
