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 body text and secondary text and the accent — stated here rather than left for you to discover.

Use the Neon Kiosk palette: #786900, #3D9B24, #0CB7A1, #02CFFA, #C2D9FE.

It is for this: Product launches that want to look lit rather than printed.

Map it as ground #C2D9FE, body text #786900, secondary text #3D9B24, and one accent #3D9B24 with #111111 printed on it. That mapping does not clear WCAG AA on body text and secondary text and the accent — body 3.84:1, secondary 2.48:1, accent 2.48:1. Fix the named role against the ground before shipping; do not ship the pair as given.

Do not use it for: Accessibility-first work — the light steps fail on white.

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 5.7 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 180 — 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.
