lol, the website reminds me of tropes like the professional cleaner whose house is messy, the chef who eats instant noodles at home, or the haut couture fashion designer who only wears jeans and tees. The colour expert whose website is monochrome.

My impression is that they are a compression expert, not a color expert. Make sense they chose uniform flat colors :D

.0037. IIRC it is possible to get a better score by looking around the screen, your peripheral vision might be somehow more sensitive.

I can see what they mean about .02 though. If I weren’t specifically looking for difference that’s where the colors become less noticeable.

I got a 0.0035. I'm on a Dell U2724D monitor which is supposed to have decent color accuracy and I cranked up the brightness and contrast to a maximum so I'm sure that helped a somewhat. I also noticed squinting and closing my eyes for a bit sometimes helped when I felt stuck.

I'm on a Vivo X300 pro in a dim room, max brightness. Some of these looked impossible but then suddenly I'd see the line.

0.0043, but to be honest, I could probably do better if I changed my monitor's settings. But I have it setup with low brightness for night time lights off viewing that won't wake me up.

Maybe he understands the field so much that he prefers to exercise it minimally in his hobby. Or maybe he just can't decide. It also makes perfect sense for a study in colors to be against a neutral background.

He’s talking about minifying CSS colors and I’m not sure if it is what I think it is.

Do CSS minifier really adjust the colors in the CSS files to get better compression rates or to reduce the number of rules in the CSS?

Same score here on my MBP with an absolutely filthy screen. Reckon I could top the leaderboard if I cleaned it.

This is an amazing deep dive into color difference measurements and how sensitive the math is. The idea that we really need to save characters - bytes - in CSS when we have so many web sites chewing through 49 MB with the enshitification of the web is hard to reconcile.
