Harmony and structure
Four hues are spaced around the wheel in two complementary pairs. It is the richest scheme, and the hardest to balance.
In this palette the hues fall in the green, cyan, violet, red and teal families, spread across 275 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.
Temperature and mood
Overall the palette is temperature-balanced: 1 of its 5 chromatic colors lean warm and 1 lean cool. Its average chroma of 0.148 makes the saturation rich.
That combination suits app and product marketing, event posters and social media graphics, and it is a good fit when you want a design to feel lively, bold and full of contrast.
Accessibility and contrast
The strongest pairing is Mustard (#9CD434) with Teal (#0E796A) at a contrast ratio of 2.99:1, which is below the WCAG AA minimum of 4.5:1. Across all 10 possible pairs, 0 reach the 4.5:1 AA level for normal text and 0 more reach 3:1 for large text.
No other palette color reaches 4.5:1 on the background (#9CD434), so this page suggests #00201B for text, a darkened Teal that reaches 9.71:1. 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: #9CD434 as the background, #CA5428 for cards and surfaces, #BB75DB as the primary brand color, #1EBDEB as the accent, and #00201B for text (a computed darker shade of Teal, because no palette color is readable on that background). A reliable starting split is 60% background and surface, 30% primary and 10% accent.
Let one hue take most of the space and use the others sparingly. Control the mood with lightness and saturation rather than hue.
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.
