How this palette was built · no hex was chosen by hand
The catalog states a recipe — scene from hue 24 and 214 — 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.
