Common Use Cases

Web designers picking brand colors. Developers populating CSS variables and theme files. UI designers building color systems with consistent contrast. Digital artists matching colors from reference images. Marketers ensuring brand consistency across platforms.

Tips

For accessibility, check the contrast ratio between text and background — WCAG recommends 4.5:1 for body text and 3:1 for large text.
Use HEX with alpha (e.g. #ff000080 for 50% red) for semi-transparent colors when supported.
Modern CSS also supports oklch(), color-mix(), and color() for more advanced palette work.
