Primary, Secondary, and Accent usually carry the strongest brand character. Keep their jobs distinct so emphasis remains predictable.

Color Palette Visualizer
Assign your palette to semantic roles, then stress-test it across six realistic interface directions before you commit colors to a product or brand system.
Preview, not certification. Colorrow flags key text contrast problems here, but one passing palette does not make a complete interface WCAG compliant.

Key text pairings
Give every color a job before polishing the screen
A semantic role describes what a color does rather than where a specific HEX value happens to appear. Background and Surface define the canvas, Primary and Secondary establish action hierarchy, Accent creates focused emphasis, Text carries content, and Border separates structure. When the palette changes later, components can keep their meaning while the actual colors move.
Background, Surface, and Text determine how comfortable the interface is to scan. These combinations deserve contrast review before decorative details.
Border supports grouping and control boundaries. It should clarify layout without competing with content or main actions.
A palette strip cannot show hierarchy
Two colors can look balanced side by side and still fight when one becomes a page background and the other becomes body text. Switching between landing, dashboard, mobile, commerce, brand, and editorial contexts exposes different densities, surface relationships, and action patterns without pretending the mockups are finished products.
Contrast is contextual, not a palette-wide badge
The warning panel checks the Text role against surfaces that actually carry small text in these previews. A passing pair is useful evidence, but it does not evaluate focus indicators, non-text contrast, states, images, typography sizes, motion, semantics, keyboard behavior, or every component in a real interface.
Move from palette to usable system
- Start with the quiet roles.Assign Background, Surface, Text, and Border first. These choices establish readability and density.
- Add action hierarchy.Use Primary for the action that should win attention, Secondary for supporting actions, and Accent sparingly for signals or selected states.
- Switch contexts.A palette that works in a spacious landing page may feel too loud in a dense dashboard or too weak in an ecommerce CTA.
- Check the real implementation.Copy the semantic CSS, then test final text sizes, controls, focus states, and component boundaries with actual content.
