#3B82F6 (Blue-500)
Output
Primary: #3B82F6, Secondary: #F67B3B (Orange), Accent: #1E40AF, Neutral: #6B7280, Background: #F3F4F6

Troubleshooting
Colors look too similar or lack contrast
Solution
Try a different harmony type. Complementary and triadic schemes produce more contrast than analogous. Also adjust the brightness slider to spread colors across the lightness range.
Generated colors feel too saturated or vibrant
Solution
Use the saturation slider to reduce intensity. Professional palettes often use muted tones (40-60% saturation) for primary colors with sparing use of high-saturation accents.
Text is hard to read on colored backgrounds
Solution
Check the accessibility contrast ratio shown for each pair. Aim for at least 4.5:1 for normal text (WCAG AA). Use darker text on light backgrounds or vice versa.
CSS export does not work in older browsers
Solution
CSS custom properties require IE11+. For legacy support, manually copy the HEX values or use a PostCSS plugin to transform variables to static values.
Frequently Asked Questions
Which harmony style should I use?
Complementary creates high contrast (good for CTAs). Analogous uses adjacent hues for a harmonious feel. Triadic gives vibrant balance. Tetradic offers the most variety. Monochromatic creates elegant single-hue designs.
Can I use these colours in my brand or website?
Yes. The generated HEX, RGB and HSL values and the CSS custom properties are free to use in any project. The Export CSS button gives you a ready-to-paste :root {} block.
What is a color palette generator?
A color palette generator is a tool that creates harmonious sets of colors based on color theory principles. It takes a seed color and applies mathematical relationships (like complementary or analogous) to produce colors that work well together.
How do I choose the right seed color?
Start with your brand's primary color — often the color of your logo or the emotion you want to convey. Blue suggests trust, green implies growth, red conveys energy. The generator will build the rest of the palette around it.
What is the difference between complementary and analogous palettes?
Complementary colors sit opposite each other on the color wheel (like blue and orange), creating high contrast. Analogous colors sit next to each other (like blue, teal, and green), creating a more harmonious, low-contrast feel.
Can I use these palettes for commercial projects?
Yes. All palettes generated by this tool are free to use for personal and commercial projects. No attribution is required.
How do I export colors for developers?
Use the "Export as CSS" button to generate CSS custom properties like `--color-primary: #3B82F6;`. These can be pasted directly into a stylesheet and referenced throughout your project.
What makes a color palette accessible?
Accessible palettes have sufficient contrast between text and background colors (at least 4.5:1 for normal text). They also avoid relying solely on color to convey information. Use the built-in contrast checker to verify.
