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

Use the Coral Market palette: #872C29, #F27168, #F9EFDA, #036568, #92F9FC.

It is for this: Commerce landings where the coral is the button and nothing else.

Map it as ground #F9EFDA, body text #872C29, secondary text #036568, and one accent #F27168 with #111111 printed on it. That mapping does not clear WCAG AA on the accent — body 7.59:1, secondary 6:1, accent 2.51:1. Fix the named role against the ground before shipping; do not ship the pair as given.

Do not use it for: Health interfaces — coral sits too near a danger red.

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 15 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 26 and 198 — 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.
