What can the palette tools do?

Batch operations on palettes: compare several at once, deduplicate near-identical colors, find nearest colors by Delta E, and reduce to N colors.

A measure of the perceived difference between two colors. Smaller Delta E means the colors look more alike; it's used to find or merge near-duplicates.

How do I clean up a messy palette?

Run deduplicate to merge colors within a small Delta E, then reduce to your target count to get a tidy, workable set.

Dedup Threshold ΔE00 5.0 Reduce to N Colors 5 Colors

Results

Similar colors are clustered by Delta E00; reduction uses Lab-space clustering

Delta E Nearest Match

Smaller ΔE00 = closer; 0-1 nearly invisible, 1-2 very close, 2-10 visible difference

About Palette Tools

Batch palette operations: compare palettes side by side, deduplicate by Delta E, and reduce to N colors. Essential for design system color governance and cleanup. Deduplication, comparison, and reduction across multiple palettes run as batch operations — no more manually checking one swatch against another for near-duplicates.

Useful when a team's palette files have accumulated clutter over the years — a periodic cleanup pass measurably reduces redundant colors in a design system.
