Palette Analyzer

Paste any set of hex colors and get an OKLCH-based diagnostic: lightness spread, near-duplicate detection, chroma balance, and hue span. Includes a perceptual fix for common issues.

What each metric means

L range (Lightness spread)

Difference in OKLCH L-value between the lightest and darkest color in the palette. A range of less than 25% usually means the palette will appear flat when used in pixel art.

ΔE (Delta E)

Perceptual distance between two colors in OKLCH space. Values below ~0.08 indicate colors that are visually very difficult to distinguish in pixel art context.

C range (Chroma spread)

Spread in colorfulness/saturation across the palette. High C range means the palette includes both muted and saturated colors.

Hue span

The range of hue degrees covered by chromatic colors. Larger span = more varied hue relationships (analogous is narrow, complementary or triadic is wider).

Health score

This site's own diagnostic score (0–100) based on measured OKLCH factors. Not an industry standard. Starts at 100; deductions applied for detected issues.

Limitations

• • The automatic fix is a heuristic — it prioritizes lightness separation and may change colors more than expected.
• • The health score is this site's own metric, not an industry-standard measurement.
• • All computation runs in the browser. No colors are sent to a server.
