Woah sweet article! Wasn't quite clear to me how perceived brightness related to WCAGs color contrast. For example, did using Lightness values end up correlating to similar contrast values? Looking at the contrast for your badges, it seems like no.pic.twitter.com/ojxixPtbSv
In other words, did you still have issues satisfying the WCAG AA requirement after "flattening" the perceived brightness of your color pallet?

The CIELAB lightness model isn't a direct proxy for WCAG contrast calculations, but it was close enough (and sufficiently deterministic) to give us the tools to get in close range, and then fine tune from there.

There was still a lot of hand-tuning to do, which was actually one of our main goals in building the tool — to give direct feedback to a human making choices, rather than build a purely procedural generator.
