🔬 How It Works
Unlike AI-based tools that guess or use machine learning, our Color Palette Generator uses proven mathematical algorithms and color theory principles for scientifically accurate, reproducible results every time.
📐 Mathematical Algorithms
HSL (Hue, Saturation, Lightness) and RGB color space conversions using industry-standard formulas ensure precise color calculations.
🎨 Color Theory Rules
Complementary, triadic, analogous, and split-complementary schemes based on the traditional color wheel and centuries of design principles.
📚 Color Name Database
Comprehensive lookup tables with thousands of named colors, including HTML/CSS colors, X11 colors, and paint brand equivalents.
♿ WCAG Compliance
Real-time contrast ratio calculations using WCAG 2.1 formulas ensure your palettes meet AA and AAA accessibility standards.
🏆 Why Algorithmic > AI
✓100% Deterministic: Same input always produces same output - no randomness
✓Scientifically Proven: Based on color theory used by designers for over 100 years
✓Fast & Offline: No API calls, no server processing - instant results in your browser
✓Privacy Focused: All processing happens locally - your colors never leave your device
✓Fully Transparent: Every calculation can be verified and explained mathematically
The Only Color Palette Generator Built on Pure Mathematics & Color Science
No guesswork. No training data. No black boxes. Just proven algorithms that work the same way every time.
