well, the color scheme itself is originated from this exact website, the one currently you presumably are on… but I liked it so much I ported the palette to my Forgejo and Navidrome instances. the source code itself for the palette spec and the tools I use for generating the palette for varied software is available at git.celikci.me/egecelikci/motif.
WCAG 2.2 AA. Every text/background pair a target ships must meet 4.5:1, and UI borders and non-text indicators 3:1. Legibility comes first when the two conflict.
