Color contrast tools to check against APCA

EL introduced me to contrast.tools recently, it uses the Advanced Perception of Color Algorithm (APCA) to check the accessibility of your text based on the desired colors and the font weight + size. But importantly, it also provides a lookup table to verify how you should (possibly, probably) interpret things.

I think that APCA is being floated as the new contrast algorithm for WCAG 3.0? But I’d need to look in to it more to be sure. Apparently APCA Readability Criterion (ARC) might be a new standard for visual contrast.

Side note: I kind of wish we could get away from acronyms-within-acronyms-within-acronyms in the accessibility standards world…
