worst under protanopia

Every pair here survives protanopia, deuteranopia and tritanopia, so these five can stand for five different things.

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 — stated here rather than left for you to discover.

Use the Newsprint palette: #0E1C27, #394A60, #707D9A, #B0B4CC, #F1F0FF.

It is for this: High-density text at small sizes, where any chroma becomes noise.

Map it as ground #F1F0FF, body text #0E1C27, secondary text #707D9A, and one accent #707D9A with #111111 printed on it. That mapping does not clear WCAG AA on secondary text — body 15.36:1, secondary 3.66:1, accent 3.66:1. Fix the named role against the ground before shipping; do not ship the pair as given.

Do not use it for: Consumer apps — it reads as a wire service.

Do not add a sixth colour, do not tint the greys toward a second hue, and do not carry meaning on hue alone — once colour vision is taken away the closest two of these sit only 14.7 apart on the CIEDE2000 scale, so pair every coloured state with a label or an icon.

How this palette was built · no hex was chosen by hand

The catalog states a recipe — ramp from hue 266 — 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.
