What Is Color Similarity?
Color similarity quantifies how close two colors are visually. It is used to spot duplicates in a palette, verify brand color matching across platforms, ensure data visualization series are distinguishable, and catch subtle differences that may not be visible in a design tool but will cause inconsistency in production.
Similarity Score Interpretation
- 100%: Identical — the two colors are exactly the same.
- 95–99%: Visually identical — indistinguishable to most people.
- 85–95%: Very similar — noticeable only in direct side-by-side comparison.
- 70–85%: Similar but distinguishable — usable as related colors.
- 40–70%: Different but related — clearly distinct hues.
- Below 40%: Substantially different — different hue families.
