worst under tritanopia

These two are one colour to a reader with tritanopia. 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 the accent — stated here rather than left for you to discover.

Use the Inventory palette: #2C2213, #53482D, #787351, #9D9F87, #C7CDBE.

It is for this: Stock and fulfilment screens that run all day on a warehouse monitor.

Map it as ground #C7CDBE, body text #2C2213, secondary text #53482D, and one accent #787351 with #FFFFFF printed on it. That mapping does not clear WCAG AA on the accent — body 9.59:1, secondary 5.53:1, accent 2.95:1. Fix the named role against the ground before shipping; do not ship the pair as given.

Do not use it for: Small screens — the mid steps merge at phone brightness.

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 12.2 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 — ramp from hue 100 — 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.
