Wherever you're working with colors and text/emblems, please also consider contrast and legibility: <https://apcacontrast.com/>

While the above site is great for measuring with a modern contrast algorithm (it’s the current algorithm for the yet-to-be-released WCAG 3 accessibility standards), it’s worth bearing in mind that the WCAG 2 algorithm is somewhat different, and a legal requirement in many markets / industries. You can check your colours against that with a tool like https://www.siegemedia.com/contrast-ratio, although there are many more.

Any reference to APCA has been removed from the WCAG 3 drafts in 2023 (see https://github.com/w3c/silver/commit/d5b364de1004d76caa7ddc4...).

I am not sure what the status is.

Oh, interesting, I’d missed that. Good info, thanks!
