worst under deuteranopia

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 the accent — stated here rather than left for you to discover.

Use the Broadcast palette: #002F38, #067688, #F6F1DA, #4D2300, #ED9150.

It is for this: News and media brands wanting a confident blue and an alert orange.

Map it as ground #F6F1DA, body text #002F38, secondary text #067688, and one accent #ED9150 with #111111 printed on it. That mapping does not clear WCAG AA on the accent — body 12.65:1, secondary 4.68:1, accent 2.11:1. Fix the named role against the ground before shipping; do not ship the pair as given.

Do not use it for: Calm products — this pairing signals urgency by default.

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 21.7 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 — scene from hue 214 and 54 — 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.
