These two are one colour to a reader with protanopia. Fine while the set is read as an order; never use them to mean two different things without a label or an icon as well.

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 Bold Serve palette: #6F0003, #E50312, #F7F0DA, #024C38, #47DAAC.

It is for this: Campaign pages needing a single loud red and a green to answer it.

Map it as ground #F7F0DA, body text #6F0003, secondary text #E50312, and one accent #E50312 with #FFFFFF printed on it. That mapping does not clear WCAG AA on secondary text — body 10.99:1, secondary 4.23:1, accent 4.23:1. Fix the named role against the ground before shipping; do not ship the pair as given.

Do not use it for: Back-office tooling — it will not survive a spreadsheet.

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 9 apart on the CIEDE2000 scale, which is too close to tell apart, 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 28 and 168 — 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.
