Color Tool

Create harmonies, extract colors from photos, check WCAG accessibility, simulate color blindness — all with precise color science algorithms.

FeaturesCore Capabilities

Color Harmonies

6 Harmony Types

Complementary, Analogous, Triadic, Split Complementary, Tetradic, and Monochromatic — generated from precise HSL calculations.

Photo Extraction

K-Means Clustering

Extract dominant colors from any photo using K-Means++ initialization with CIEDE2000 perceptual distance.

Accessibility

WCAG 2.1 Contrast

Real-time contrast ratio calculation with AA/AAA level detection for both normal and large text.

Color Vision

Blindness Simulation

Simulate Protanopia, Deuteranopia, and Tritanopia using Hunt-Pointer-Estevez LMS color space matrices.

Multi-Format

7 Export Formats

Export palettes as ASE, CSS Variables, Swift, Android XML, Kotlin Compose, Tailwind CSS, or JSON.

Color Science

Precise Conversions

Full color pipeline: RGB, HSL, HSB, XYZ (D65 illuminant), CIELAB — with CIEDE2000 perceptual difference.
