Create beautiful triadic and tetradic color palettes with professional color theory principles
About Color Harmonies
Triadic (3 colors) uses equidistant HSL angles for balanced contrast. Tetradic (4 colors) creates rectangular relationships on the color wheel. Adjust angles to fine-tune harmony for your design system.

Base Color
RGB values range 0-255. HEX is web standard. Conversions maintain full precision. If you need to convert a specific HEX value for this tool, you can also use our dedicated HEX to RGB converter first.
Color Harmony
Default
Design Tip: Use triadic for vibrant interfaces, tetradic for complex branding systems requiring multiple accent colors.
Triadic Settings
Adjust the angle between triadic colors
Standard triadic uses 120° for perfect balance. Adjust for custom harmonies (90° for square, 60° for split-complementary feel).
Tetradic Settings
Adjust the rectangle aspect ratio
Ratio 1.0 creates a square (90° angles). Other ratios produce rectangular tetradic relationships for varied contrast.
Color Variations
UI System Building: Light/dark variants create consistent tint/shade scales for buttons, cards, and text contrast. For a more structured approach to variations, try the HEX shades and tints generator.
Output Options
HEX for web, RGB for screen design, HSL for color adjustment understanding. All conversions preserve hue accuracy. You can also get the HSL representation directly with our HEX to HSL converter.

Visual Preview Guidance
Colors are generated in HSL color space for perceptual accuracy. The preview shows how colors will appear on standard RGB displays (sRGB gamut). Check contrast ratios for accessibility.
Why do colors look different on print?
This tool uses RGB/HSL for screen design. Print uses CMYK with different gamut limitations. Always test print colors physically. Use a HEX to CMYK converter for an initial estimate.
Gamut Note: Some vibrant HSL colors may be outside printable CMYK gamut. For print work, convert to CMYK in your design software and adjust accordingly.
CSS Gradient Generator
Gradient Implementation Notes
Generated CSS uses modern gradient syntax compatible with all current browsers. For IE11 support, add vendor prefixes (-webkit-, -moz-). Test gradient performance on mobile devices.
Performance Tip: Complex gradients with many color stops can impact rendering performance. For hero sections, limit to 3-5 colors.

Common Designer Questions
Are these harmonies accessible?
Complementary pairs often fail contrast ratios. Always test with tools like WebAIM Contrast Checker. Monochromatic schemes with sufficient lightness difference work best.
Can I use these for branding?
Yes, but consider cultural color meanings. Tetradic schemes work well for comprehensive brand systems with primary/secondary color needs.
Why HSL instead of RGB for harmonies?
HSL represents colors in a human-perceptual way (Hue, Saturation, Lightness). Rotating hue creates perceptually balanced harmonies, unlike RGB mathematical operations.
Professional Color Workflow
Real-World Applications
UI Design Systems
Use triadic harmonies for primary/accent/neutral relationships. Export CSS for design token integration.
Brand Identity
Tetradic schemes provide versatile color families for logos, marketing materials, and digital presence.
Data Visualization
Analogous harmonies create perceptually ordered sequential data palettes with natural progression.
Display Variation: Colors appear differently across monitors (calibration, panel type). Always test on target devices.
Conversion Precision
HSL calculations maintain full floating-point precision. Display values are rounded for readability. Underlying color math remains accurate.
Pantone/CMYK Matching
This tool generates screen colors. For Pantone matching, use official Pantone guides or a dedicated Pantone to HEX converter. CMYK conversion requires professional color management.
Color Standards: Based on W3C HSL/RGB specifications. Updated for current web color practices.
