Troubleshooting
Colors Don't Look Good Together
- Try using analogous mode for naturally harmonious combinations - Use complementary mode for high contrast - Adjust your base color's saturation and lightness for better resultsInvalid HEX Code Error
- Ensure your HEX codes start with # (or omit it, both work) - Use 6 characters for full codes (#3498db) or 3 for shorthand (#3bd) - Only use valid hex characters: 0-9 and A-FBulk Upload Failed
- Check that your CSV has the correct column headers - Ensure your CSV doesn't exceed row limits (25 free, 1000 pro) - Verify all HEX codes are valid format - Make sure palette_size values are between 2 and 10Can't Copy Colors
- Enable JavaScript in your browser - Check clipboard permissions in browser settings - Try manually selecting and copying the color codesColors Look Different in My Design Tool
- Different tools may interpret RGB/HSL values slightly differently - For consistency, use HEX format when possible - Check that your design tool's color space matches (sRGB recommended)Tips for Best Results
- Start with Your Brand: Use custom or complementary mode with your brand color as the base
- Consider Context: Triadic for playful designs, analogous for professional/calming aesthetics
- Test Contrast: Ensure sufficient contrast between text and background colors for accessibility
