In this palette the hues fall in the teal and green families, spread across 21 degrees of the OKLCH hue circle. Vivid palettes keep chroma between 0.15 and 0.26, and lightness between 52% and 82%, which is why the set feels consistent.

Accessibility and contrast
The strongest pairing is Aqua (#21E9C4) with Moss (#0C815A) at a contrast ratio of 3.14:1, which is WCAG AA large. Across all 10 possible pairs, 0 reach the 4.5:1 AA level for normal text and 1 more reach 3:1 for large text.
No other palette color reaches 4.5:1 on the background (#21E9C4), so this page suggests #052015 for text, a darkened Moss that reaches 11.04:1. Check any pair you use in the contrast checker.
All five colors stay distinguishable under protanopia, deuteranopia and tritanopia simulations, which is a good sign, although it is no substitute for testing with real users.
How to use it
Suggested roles: #21E9C4 as the background, #39CBAF for cards and surfaces, #01B385 as the primary brand color, #219588 as the accent, and #052015 for text (a computed darker shade of Moss, because no palette color is readable on that background). A reliable starting split is 60% background and surface, 30% primary and 10% accent.
Use the lightest color for large areas, the mid tones for structure, and the darkest for text. Add contrast through lightness, since hue will not do it for you.
Typical uses for a vivid palette include app and product marketing, event posters, social media graphics and entertainment brands. Open it in the generator to lock the colors you love and reroll the rest, or in the visualizer to see it on real layouts.
