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

What's My JND?

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

@keithamus cool utility! 0.0037 on a pixel 9 pro in a sunny room. Do you know if age is a factor for color perception? Would have to think sex is, if xkcd has learned me anything
@tal age must be a factor, anecdotally, sex seems to be. Also the quality of display definitely matters, but worse displays might be better to an extent!
@keithamus @tal I always thought that comic was about how m/f genders are _taught_ to name colours, rather than the physical perception of them
@Rubelicious I think it can be both, of be open to the idea of neuroplasticity in color perception.
@tal this is one of the most fascinating threads I've read in a long time 😊
