How to Create an Accessible Website Color Palette

Start with roles, not favorite swatches

Begin by listing the jobs your colors must perform. A small website usually needs a page background, elevated surface, primary text, secondary text, border, primary action, link, focus indicator, success, warning, and error. Naming roles first prevents one attractive color from being reused in places where it cannot communicate clearly.

Keep decorative colors separate from functional colors. A pale lavender may work beautifully behind an illustration but fail as body text. A saturated red may suit an accent but should not automatically become the only signal for an error.

Build the neutral foundation

Choose the background and text pair before selecting brand accents. Test the darkest text on the lightest surface and the lightest text on the darkest surface. Then add one or two intermediate text colors for captions and metadata, checking that each remains readable at its intended size.

Avoid using very light gray for essential instructions. Subtle text often looks refined in a design file but becomes difficult to read on low-quality screens, in bright light, or for people with reduced contrast sensitivity.

Assign interactive colors deliberately

Links, buttons, selected tabs, and focus rings need distinct states. Define default, hover, active, focus, and disabled colors rather than letting the browser or framework improvise them. A focus indicator should be visible against both the component and the surrounding page.

Do not depend on color alone. Underline text links in paragraphs, add icons or labels to status messages, and combine error color with explanatory text. These extra signals improve clarity for everyone, not only users with color-vision differences.

Test combinations in context

Check contrast between the exact foreground and background colors used in the interface. Semi-transparent overlays, gradients, images, and shadows can change the effective result. Test small text, large headings, icons, form borders, placeholder text, and text inside buttons separately.

Use Colorrow’s Contrast Checker while assigning roles, then preview the palette in the Palette Visualizer. A ratio is useful evidence, but the final review should also include zoomed text, keyboard navigation, grayscale viewing, and a mobile screen in bright conditions.

Document a usable palette

Store every approved color with a role-based name such as text-primary, surface-muted, action-primary, focus-ring, and status-error. Add notes about where each token may be used and which foreground colors are approved on top of it.

A documented palette prevents future pages from introducing near-duplicate grays or untested button shades. It also makes accessibility part of the design system instead of a final audit.
