How to use a color palette generator
A well-chosen color scheme is the foundation of any professional design. Picking colors at random leads to a visually confusing result; a thoughtfully composed palette creates calm, cohesion, and a recognizable identity. Our free color palette generator calculates a complete harmonious palette from a single base color â based on proven color theory principles.
Whether you are building a website, creating a presentation, designing a logo, or establishing a brand identity â a consistent color palette is the first step. The generator shows you HEX codes, RGB values, and HSL notation for every color, ready to copy into your CSS, Figma, Canva, or Adobe workflow.
The four color harmonies explained
- Complementary: Two colors opposite each other on the color wheel. Maximum contrast, strong accent â use one color as dominant and the other as accent.
- Analogous: Three to five adjacent colors on the wheel. Calm, harmonious â great for backgrounds and neutral designs.
- Triadic: Three colors evenly distributed around the wheel. Vibrant yet balanced â popular in branding and illustration.
- Monochromatic: Variations in lightness and saturation of one single hue. Sleek, professional, and easy to implement in CSS using HSL values.
Frequently asked questions
What is the difference between HEX, RGB, and HSL?âŧ
HEX (#1A6BF5) is the most widely used notation in CSS and HTML â a hexadecimal code describing red, green, and blue in six characters. RGB (rgb(26, 107, 245)) expresses the same color as three values from 0 to 255, useful for transparency via rgba(). HSL (hsl(218, 91%, 53%)) describes color through hue, saturation, and lightness â intuitive for adjusting colors while preserving the hue. All three describe the same color; only the notation differs.
How many colors should a brand palette contain?âŧ
A professional brand palette typically contains 3 to 5 colors: one primary color (dominant), one secondary color (accent), one neutral color (grey or off-white for backgrounds), and optionally a success color (green) and an error color (red) for UI applications. Too many colors make a design chaotic; too few can make it flat. The "60-30-10 rule" helps: 60% neutral, 30% primary, 10% accent.
How do I check if my color palette is accessible?âŧ
Accessibility (WCAG) requires sufficient contrast between text and background. The minimum contrast ratio is 4.5:1 for normal text and 3:1 for large text. After generating your palette, use a contrast checker (such as WebAIM Contrast Checker) to verify your combinations meet WCAG AA or AAA standards. Google also evaluates accessibility as part of Core Web Vitals and user experience signals.
Can I import the generated palette into Figma or Canva?âŧ
Yes. Copy the HEX codes from the generator and add them manually as color styles in Figma (Design panel â Local styles â +) or as brand colors in Canva (Brand Kit). In Figma you can also paste CSS values directly; in Canva the HEX code alone suffices. Adobe XD and Illustrator also accept HEX codes as color swatch input.
What is the best starting color for a professional design?âŧ
Blue is the most trusted color in B2B and professional contexts (technology, finance, healthcare). Green works well for sustainability, health, and nature. Orange and red grab attention and are popular for call-to-action elements. Purple associates with luxury and creativity. Black and dark navy convey premium quality. Choose a color that fits your target audience and sector, then build your palette around it.
