HEX, RGB, and HSL — When to Use Which
CSS accepts the same color in multiple formats. They're all interchangeable in browsers — the difference is purely about readability and workflow. HEX is the most compact; RGB is the most explicit; HSL is the most intuitive for humans because it separates hue, saturation, and lightness in a way that mirrors how we think about color.
Modern CSS also supports oklch() and oklch(), which offer better perceptual uniformity — but HEX, RGB, and HSL remain the formats used by virtually every design tool, design system, and developer today.
Common Use Cases
Design system token conversion
Convert brand colors from a designer's HEX values to the HSL format required by your CSS custom properties.
Building light and dark themes
Convert colors to HSL to generate lighter or darker variants by adjusting the L (lightness) value.
Cross-tool consistency
Match a Figma HEX color to a Tailwind CSS HEX, or verify an RGB value from a color picker.
CSS variable definitions
Define CSS custom properties in HSL format so you can compose color variants programmatically.
Email template colors
Some email clients require hex; others support rgb(). Convert to whichever works for your context.
Verifying color output
Check that a programmatically generated color (from a chart library or canvas) matches the intended brand color.
