Algorithmic Theming Engines

> APCA models how human eyes actually perceive contrast, factoring in font weight, spatial frequency, and ambient light — a genuine improvement over the WCAG 2.x formula. […] The research behind it is peer-reviewed and substantive

That's what the author claims, but I have not seen any evidence that it is actually true. In a ticket where they were asked to provide peer review, they instead linked to a bunch of blog posts that in my opinion do not qualify as peer review: https://github.com/w3c/wcag3/issues/29

Also, it is not as if the WCAG 2 formula would not model how humans actually perceive contrast.

How does someone write an article like this without ever once thinking "I should include some images that demonstrate what kind of colors this will automatically generate. Maybe even stick in an editable bit of html/css to let readers play with it themselves."

An article on theming without any visuals :-(
