CSS Color Studio

Explore palettes and copy CSS-ready colour values

CSS Color Studio combines a palette browser with a colour picker. Browse the included palettes, search by theme, inspect individual swatches, and copy HEX, RGB, or HSL values for use in CSS, design tokens, prototypes, and component libraries.

How to use CSS Color Studio

1. Browse or search palettes that fit the project mood or colour family.
2. Select a swatch to copy its value, or use the picker to create a custom colour.
3. Switch between HEX, RGB, and HSL when your stylesheet or design system needs a different format.
4. Test the chosen colours with the text, surface, and interaction states used in your interface.

Colour choices that work in interfaces

A palette is a starting point rather than proof of accessibility. Keep enough contrast between text and its background, reserve distinct colours for focus and error states, and use more than colour alone to communicate status. Naming stable roles such as --color-text and --color-surface makes a palette easier to maintain than scattering raw values through a codebase.

From a palette to a maintainable design system

Choose colours by role before choosing them by name. Most interfaces need a text colour, muted text, surface, raised surface, border, primary action, focus ring, success, warning, and error treatment. Define those roles as CSS custom properties, then test them in light and dark contexts. This makes a later palette change a token update instead of a search through every component.

HEX is compact and common in CSS. RGB is useful when working with channels or alpha values, while HSL can make hue and lightness adjustments easier to reason about. None of these formats automatically creates a usable scale. Check hover, focus, disabled, selected, and error states, then verify text contrast at the actual font size and weight used by the product.

Practical palette workflow

1. Pick a neutral surface and readable text pair first.
2. Add a primary colour for actions, then define a visible keyboard focus treatment.
3. Use semantic names such as --color-action-primary instead of names tied to one hue.
4. Test charts, badges, alerts, and icons without relying on colour as the only signal.
5. Save the final values with the component or token documentation that explains their role.
