HI Lea @LeaVerou > .._.levels don't mean anything outside their algorithm, .... (e.g. `wcag-aa`),.._ Not only that, but: **AA** encompasses two discrete ratios, 3:1 and 4.5:1, and **AAA** encompasses three distinct ratios, those of AA, and the additional 7:1. And the 3:1, 4.5:1, and 7:1 as calculated by WCAG 2 math are _different than every other contrast math,_ and the actual results skew differently relative to the overall total luminances being tested as does every other contrast math or method, ever... And I know you know this but for anyone reading along at home, among the reasons is that there is no such thing as an absolute contrast: **Contrast is not real,** just as color is not real, it is a context sensitive perception and about as hard to nail down as grasping a wet bar of soap in the middle of a typhoon while being chased by hungry wild geese. -- GitHub Notification of comment by Myndex Please view or discuss this issue at https://github.com/w3c/csswg-drafts/issues/7356#issuecomment-1159781187 using your GitHub account -- Sent via github-notify-ml as configured in https://github.com/w3c/github-notify-ml-config
