Danger semantics — a warm hue is already in the middle of the set.
What was measured
- Closest neighbours
- ΔE00 30.5
- how alike two adjacent swatches look
- Darkest to lightest
- 6.5:1
- WCAG contrast across the set
- Lightness covered
- 48 pts
- of OKLCH lightness, 0–100
- Under colour blindness
- ΔE00 20
- worst under tritanopia
Every pair here survives protanopia, deuteranopia and tritanopia, so these five can stand for five different things.
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 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 — series from hue 44 — 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.
