Apologies if this sounds completely defeatist, but wouldn’t it be better to just mostly get rid of colors in product design? That is, yes, you absolutely want to use color for branding and recognizability, but given the fact that widely deployed color models and accessibility metrics do not completely reflect the reality of human color perception, using them to convey information is just not worth the trouble.

Again, there are exceptions to everything, but WCAG 2.1 says UIs shouldn’t fully rely on color to convey information (please correct me if I am wrong), the same goes for icons.

I can see how other sectors and industries will treat this differently (think color bands on resistors or topographical maps), but for me, creating a SaaS product with a focus on accessibility, I have almost completely given up on this topic.

Charts, statistics and so on are way easier to make accessible when using good old HTML tables.

The increase in product quality is marginal when optimizing for color.
