Hi @bkimmelSQSP Brent, I just saw this — this is possible with APCA, the new contrast method for WCAG 3.0, but it's not really useful for WCAG 2.x, as the contrast math/method for WCAG 2.x is not perceptually uniform (not even close). This is a known issue with WCAG 2 contrast that is being corrected with a complete overhaul for WCAG 3. There is a constant-contrast demo of APCA after clicking on the "research mode" at the [SAPC development site.](https://www.myndex.com/SPAC/) And here are some brief articles with visual examples of how WCAG 2 fails and comparisons to WCAG 3's APCA: ### _Part I:_ - [**Orange You Wondering About Contrast?**](https://gist.github.com/Myndex/1dadb6dcac596f1cd7a5686a076f697f) Answering some contrast questions, and demonstrating a real solution to the infamous orange conundrum. ### _Part II:_ - [**The Lighter Side of Dark Backgrounds**](https://gist.github.com/Myndex/c30dba273aa5eca426ad9f5200917c9d) An article comparing some parts of APCA with the old WCAG 2 contrast methods. ### _Part III:_ - [**WCAG 2 vs APCA Contrast Shootout**](https://gist.github.com/Myndex/069a4079b0de2930e72d5401bde9af98#wcag-2-vs-apca-contrast-shootout) A gist answering some recent questions regarding APCA, and comparisons and examples of the old (WCAG 2 1.4.3) and the new WCAG 3 with APCA. -- GitHub Notification of comment by Myndex Please view or discuss this issue at https://github.com/w3c/csswg-drafts/issues/6305#issuecomment-964259877 using your GitHub account -- Sent via github-notify-ml as configured in https://github.com/w3c/github-notify-ml-config
