Quick Start

How to Create a Color Palette Online

Start with one base color and build related colors around it using a color harmony. You can then lock the swatches you want to keep, regenerate the others, test contrast, and export the finished palette for your website, brand, or UI project.

  1. Choose a starting color. Enter a HEX value or select a color visually.
  2. Select a color harmony. Try complementary, analogous, triadic, monochromatic, split-complementary, or tetradic.
  3. Generate and refine. Lock the colors you like and regenerate only the remaining swatches.
  4. Validate the palette. Check contrast and preview the colors with color-vision simulations.
  5. Export your colors. Move the finished palette into CSS, Tailwind, SCSS, JSON, SVG, or PNG.

Choose the Right Color Harmony

Color harmony describes how colors relate to each other on the color wheel. The right harmony depends on whether your design needs strong contrast, subtle variation, visual consistency, or a wider range of distinct colors.

  • Complementary — colors from opposite sides of the color wheel for strong visual contrast and prominent accents.
  • Analogous — neighboring hues that create a softer, more connected visual style.
  • Triadic — three evenly spaced hues that provide variety while maintaining visual balance.
  • Tetradic — four related hues for designs that need a wider and more expressive color range.
  • Split-Complementary — useful when you want contrast without the intensity of a direct complementary pair.
  • Monochromatic — variations of one hue for simple, consistent interfaces and brand systems.

Refine and Lock Colors in Your Palette

Found a color that works? Lock it before generating again. Only the unlocked swatches will change, which lets you refine a palette gradually instead of starting from scratch after every generation.

  • Press L to lock/unlock the selected color
  • Keyboard navigation with ← → arrow keys
  • Press C to copy HEX to clipboard
  • Ctrl+Z / Ctrl+Shift+Z for undo/redo (30 states)

Inspect HEX, RGB, HSL and Other Color Values

Open any palette color to inspect the values you may need for design or development. Copy individual formats directly, explore lighter tints and darker shades, and use the same color consistently across different tools and workflows.

  • HEX, RGB, HSL, HSB, CMYK, LAB, LCH, XYZ, LUV, HWB
  • Color name detection against a curated name database
  • Tints & shades scale (10 lighter + 10 darker variations)
  • Gradient preview derived from palette colors

How to Create an Accessible Color Palette

An accessible palette needs more than attractive swatches. Text, buttons, links, form controls, icons, and other important interface elements must remain readable and distinguishable against their backgrounds.

For WCAG 2.2 contrast guidance, normal text generally needs a contrast ratio of at least 4.5:1 for Level AA, while large text needs at least 3:1. Level AAA uses a higher 7:1 ratio for normal text.

  • Check text against its actual background color.
  • Test buttons, links, form controls, and important states.
  • Preview colors for common color-vision deficiencies.
  • Do not rely on color alone to communicate errors, warnings, success states, or other important information.
  • Test the palette inside real UI components before finalizing it.

Quick Contrast Reference

AA Normal Text

Minimum contrast: 4.5:1

AA Large Text

Minimum contrast: 3:1

AAA Normal Text

Minimum contrast: 7:1

Preview Your Palette for Color-Blind Users

Colors that look clearly different to one person may appear much more similar to someone with a color-vision deficiency. Preview the complete palette before using color differences for navigation states, charts, buttons, badges, alerts, or other important interface elements.

  • Protanopia (red-blind)
  • Deuteranopia (green-blind)
  • Tritanopia (blue-blind)
  • Achromatopsia (complete color blindness)

Export Your Palette to CSS, Tailwind, JSON, SVG and PNG

Move your final colors directly into design and development workflows instead of rebuilding the palette manually. Copy developer-ready variables or download visual formats for documentation, handoff, and sharing.

How to Choose a Color Palette for a Website

A useful website palette gives every color a clear job. Start with a small set of core colors, then expand them into lighter and darker variations only when the interface needs them.

Give Every Color a Purpose

  • Primary color: important brand elements and main actions.
  • Secondary color: supporting elements and secondary actions.
  • Accent color: highlights and elements that need attention.
  • Background and surface colors: pages, navigation, cards, panels, and modals.
  • Text colors: headings, body copy, labels, and secondary text.
  • Semantic colors: success, warning, error, and informational states.

How Many Colors Should a Website Palette Have?

There is no fixed number for every website. A good starting point is a small core palette with clearly defined roles rather than many unrelated colors.

Once the core palette works, create lighter and darker variations for hover states, focus states, borders, disabled controls, backgrounds, and other interface requirements.

Test combinations in real buttons, text, navigation, forms, cards, and backgrounds before deciding that a palette is finished.

Generate

Choose a harmony mode and generate your first palette

Start with a harmony family such as Square, Complementary, Triadic, or Analogous, then compare the resulting five-color palette with its color-blindness simulation before committing to a direction.

Tune

Refine the base color before regenerating harmonies

Use the wheel, HEX input, eyedropper, and base-color refinement controls for brightness, saturation, hue shift, and temperature so locked palette colors stay aligned with your intended direction.

Review supporting colors and base color information

Generated supporting colors help users expand beyond the original five swatches while the base color info panel gives a focused place to inspect the source color and jump into a deeper detail page.

Use Your Palette in Branding, Web Design, and UI Systems

A useful palette should move easily from color exploration into real design work. Refine your core colors, build shade scales, extract colors from visual references, or turn your palette into production-ready gradients.

  • Brand design: build primary, neutral, and accent colors from one starting hue
  • UI systems: validate accessible combinations before handing tokens to developers
  • Creative exploration: test rainbow color palette directions, monochrome sets, and bold complementary palettes
  • Production handoff: continue into the Tailwind color generator or the CSS gradient generator without rebuilding colors
