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 Also great for suddenly seeing how dirty your screen is 🤢
@joface this is the one consistent piece of feedback. Maybe we should start a support group.
@keithamus @joface I pulled out a cloth and wiped my screen down to get the optimal score I could 😂 glad it's not just me
@Lukew @keithamus @joface I was complaining about my dirty screen protector… when I realized the problem was really my glasses. 😳😬

@a
Adding my own for posterity, using a Viewsonic 27" monitor. WIll have to try it at home on my other monitors for comparison.
