How to use a palette

Every palette on Omni Color can be used directly in your project. The typical workflow is:

  1. Choose a base palette
    Pick a collection that matches your product category and desired mood.
  2. Assign roles
    Decide which colors will serve as background, surface, primary action, accent, text, and semantic states (success, warning, error, info).
  3. Expand into scales
    Use the shades generator to extend each core color into a full 50–950 scale.
  4. Verify contrast
    Test every foreground/background pair with the contrast checker. Adjust lightness if any pairing fails AA.
  5. Test under CVD
    Run the palette through the color blindness simulator. Ensure status colors remain distinguishable.
  6. Export
    Copy as CSS variables, JSON tokens, or SVG — ready to drop into your project.

What makes a good palette?

  • A clear hierarchy. One dominant color, one or two accents, and a solid neutral base.
  • Sufficient contrast. Every text/background pair reaches at least 4.5:1.
  • Lightness variety. Colors differ in lightness, not just hue — this ensures usability in grayscale.
  • Semantic roles. Success, warning, error and info are clearly distinct from each other.
  • CVD survivability. Color meaning is never carried by hue alone.
  • Dark mode readiness. Each color has a considered dark-mode counterpart.

Generate a custom palette

If none of the curated collections fit, the palette generator can create a custom palette from any base color using 21 different modes.

Frequently asked questions

What is a color palette?

A color palette is a curated set of colors used together in a design. Palettes typically include one or two brand colors, a set of neutrals, and a few semantic colors for states like success and error. Well-designed palettes feel intentional — every color earns its place.

How many colors should a palette have?

Most professional palettes have 5–8 core colors, which then expand into shade scales (like 50–950) for each hue. More than 8 distinct hues usually makes a palette feel chaotic; fewer than 4 usually feels incomplete.

Can I use these palettes in commercial projects?

Yes. Colors themselves are not copyrightable. Every palette on Omni Color can be used freely in any project, commercial or personal, without attribution.

How do I build my own palette?

Start with one anchor color, generate a harmonious set with the palette generator, expand each hue into a 50–950 scale, verify contrast for the pairs you plan to use, and test under color blindness simulation. Our guides walk through the full process.

Are the palettes accessible?

Accessibility depends on which colors you pair together. All palettes in the Accessibility section are verified to pass WCAG AA for their intended foreground/background pairs. Other palettes may require adjustment depending on how you use them.
