Common use cases

CSS hsl() from a design RGB

Paste R, G, and B from Figma or a screenshot and copy hsl() for modern stylesheets.

Tweak hue without rebuilding RGB

Keep saturation and lightness fixed, spin hue, and copy the new rgb() for a palette variant.

Handoff between HEX and HSL tools

Use HEX to RGB Converter for a #rrggbb code, then this converter for the HSL path.

Teaching color models

Show why gray has hue 0, why lightness 50% is a pure hue, and how 100% lightness becomes white.

Examples

• Pure red: rgb(255, 0, 0) → hsl(0, 100%, 50%).
• Tailwind blue-500: rgb(59, 130, 246) → hsl(217, 91%, 60%).
• Neutral gray: rgb(128, 128, 128) → hsl(0, 0%, 50%). Hue is 0 because gray has no saturation.
• HSL to RGB: hsl(120, 100%, 50%) → rgb(0, 255, 0) (pure green).

Pro tips

• Hue 0 = red, 120 = green, 240 = blue. 360 wraps back to 0.
• At 0% saturation the color is gray and hue has no visible effect until you raise S.
• Lightness 0% is black, 100% is white, 50% is the 'pure' hue at full saturation.
• Out-of-range RGB is clamped to 0-255; S and L clamp to 0-100.
• Need HEX, CMYK, contrast, or a tint-shade ramp? Open HEX to RGB Converter.

Frequently asked questions

How do I convert RGB to HSL?

Enter red, green, and blue from 0 to 255. The tool computes hue (0-360), saturation (0-100%), and lightness (0-100%) and shows hsl() CSS you can copy. Example: rgb(255, 0, 0) is hsl(0, 100%, 50%).

Can I convert HSL to RGB?

Yes. Edit H, S, or L and the RGB channels, rgb() CSS, HEX, and swatch update at once. Hue wraps at 360; saturation and lightness clamp to 0-100.

What do H, S, and L mean?

Hue is the color angle on the wheel (0 red, 120 green, 240 blue). Saturation is how vivid the color is (0% gray, 100% full color). Lightness is how light it is (0% black, 50% pure, 100% white).

Why is hue 0 for gray?

Grays have 0% saturation, so hue is undefined and this converter reports 0. Changing hue on a gray does nothing until you raise saturation.

Is this the same as HEX to RGB?

No. HEX to RGB Converter is for #rgb / #rrggbb codes, plus CMYK, contrast, and token snippets. This tool is the bidirectional RGB ↔ HSL path. Pair them when a spec mixes HEX and HSL.

Does my color leave the device?

No. The RGB to HSL Converter runs entirely in your browser. Values are not uploaded or stored on a server.
