A suggested mapping · derived, then measured
Five colours are not an interface, so this is an offer rather than a token set. It does not clear WCAG AA on body text and secondary text and the accent — stated here rather than left for you to discover.

How this palette was built · no hex was chosen by hand
The catalog states a recipe — spread from hue 204 — and the five colours are derived from it in OKLCH, where a step of lightness is a step your eye agrees with rather than one the hex numbers agree with. That is why the numbers above are properties of this palette rather than claims about it.
