Thinking in pairings

Why audit the whole palette

Checking contrast between two colors is useful. Checking contrast across every pairing in a palette is how you actually understand what a set of colors can do. A palette might look cohesive in a swatch grid but offer very few readable text-on-background combinations. This audit makes those relationships visible at a glance.

Reading the results

The summary tells you how many of the palette's pairings pass AA and AAA at different text sizes. The strongest pairings section surfaces your best options for body text. The contrast matrix shows every relationship at once — green cells pass, amber cells are borderline, and pale cells fail. Rows represent text color, columns represent background.

What the scores mean in practice

A palette with "strong" coverage gives you multiple safe text/background combinations — more flexibility for UI, editorial, and brand work. "Moderate" means you have options but need to be deliberate. "Limited" doesn't mean the palette is bad — it may be excellent for accents, illustration, or data visualization — but you'll need to be careful about where you put text.

Custom palettes

This tool works with any colors, not just Huelib palettes. Switch to "Custom palette" mode to enter your own hex values, add or remove colors, and audit your real-world brand or product palette. This is useful for evaluating an existing design system or testing a palette you're building from scratch.

Part of a workflow

Use this audit alongside Huelib's other tools. TheContrast Checkertests individual pairs in detail. TheColor Blindness Simulatorshows whether colors remain distinguishable under different forms of color vision deficiency. TheToken Mapperhelps assign roles. Together they give you a practical picture of whether your palette is ready for production.
