Common Use Cases
Define a product colour system
Generate related colours for primary actions, secondary surfaces, accents, borders, and feedback states.
Explore illustration palettes
Build harmonious sets for posters, charts, icons, and artwork before committing to detailed production work.
Create data-visualisation colours
Start with distinct hues for series, categories, or statuses, then test them for contrast and colour-vision accessibility.
Derive variants from a brand colour
Use a base colour to explore lighter, darker, complementary, analogous, or triadic options.
Why is this tool useful?
Structured colour relationships
Generate colours using recognised harmony rules instead of selecting unrelated swatches by eye.
Reusable colour values
Copy exact hex or CSS variable values so design and implementation use the same palette.
Rapid comparison
Change the base colour and immediately compare several coordinated alternatives.
Best Practices
- ✓ Assign a purpose to each colour, such as background, text, action, warning, or data series, rather than treating the palette as a decorative set.
- ✓ Check text and icon contrast against the exact backgrounds where they will appear, using WCAG contrast criteria where applicable.
- ✓ Test the palette in grayscale and with colour-vision simulations so meaning does not depend on hue alone.
- ✓ Use neutral colours for most surfaces and reserve saturated colours for actions, emphasis, and status.
- ✓ Store approved colours as design tokens or CSS variables with semantic names, not only names such as blue-500.
Practical examples
Base color: #2563EB, harmony: complementary.
A palette built around blue and its opposite hue, suitable for separating primary actions from attention states. Verify text contrast before assigning the colors to UI roles.
Base color: #0F766E, harmony: analogous.
A set of neighbouring teal, green, and blue-green tones that feels cohesive. Add a neutral background and a high-contrast text color rather than using every generated color equally.
Frequently Asked Questions
Color harmony refers to combinations of colors that are pleasing to the eye because they follow specific relationships on the color wheel. Common harmonies include complementary (opposite colors), analogous (adjacent colors), and triadic (evenly spaced thirds).
An analogous palette uses colors that sit next to each other on the color wheel, creating a cohesive, calm look. A triadic palette uses three colors evenly spaced (120° apart), creating a more vibrant, high-contrast combination.
A monochromatic palette uses variations of a single hue, different lightness and saturation levels, creating a refined, elegant look that's easy to apply consistently throughout a design.
