This step-by-step guide walks you through the process using LevnTools Color Picker, a free browser-based tool that handles everything locally on your device. No software to install, no account to create, and no files uploaded to external servers. Follow these steps to complete the task in under a minute — updated for 2026.
Select your base color
Use the color picker to select the color for which you want to find complements. You can click on the color wheel, enter a HEX code, or adjust HSL sliders.
View the complementary color
The tool automatically calculates and displays the complementary color — the one directly opposite on the color wheel. This pair creates maximum visual contrast and energy.
Explore other harmonies
Switch between harmony modes to see analogous (adjacent), triadic (three evenly spaced), split-complementary, and tetradic color relationships. Each mode generates different color combinations.
Copy and use the colors
Copy the HEX, RGB, or HSL values for any color in the harmony set. Use these color combinations in your design to create visually balanced and appealing layouts.
Pro Tips
- Complementary colors create strong contrast — great for call-to-action buttons against a background.
- Use the 60-30-10 rule: 60% dominant color, 30% secondary, 10% accent for balanced designs.
- Desaturate one of the complementary colors to avoid visual clashing in large areas.
Common Issues & Fixes
Issue: The complementary colors look too harsh together.
Fix: Reduce the saturation of one or both colors. Using tints (lighter) or shades (darker) of the complements softens the contrast.
Issue: I cannot find a complementary color that matches my brand.
Fix: Try split-complementary instead — it gives two colors near the complement, offering more flexibility while keeping visual interest.
