About Color Converter

Color Converter translates colors between HEX, RGB, HSL, and HSV for frontend CSS, design handoff, and theme token cleanup.

Enter #4f46e5, rgb(...), or hsl(...) to normalize the color into copyable formats.

How to use Color Converter

Paste a HEX, RGB, RGBA, HSL, or HSLA color value.
Convert it and review HEX, RGB, HSL, and HSV outputs.
Use the swatch preview, then copy one format or all formats.

When you would use it

Convert a design HEX value into CSS rgb() or hsl().
Adjust lightness and saturation in HSL while testing hover states.
Normalize color token values while cleaning up a theme.

Color formats and caveats

HEX, RGB, HSL, and HSV describe the same color through different coordinates. This converter preserves the RGB color itself; alpha in RGBA or HSLA input is accepted but not preserved in output. RGB channels must be valid numeric values.

3-digit HEX expands to 6-digit HEX.
RGB channels must stay between 0 and 255.
HSL uses percentages for S/L and wraps hue around 0 to 360 degrees.
HSV is common in pickers, while HSL is often easier for CSS theme tuning.

Color Converter FAQ

Can it convert HEX to RGB and RGB to HEX?: Yes. HEX input produces RGB/HSL/HSV, and RGB input produces HEX/HSL/HSV.
Why is alpha missing from the result?: The tool currently focuses on opaque color conversion, so RGBA/HSLA alpha is ignored.
Are my colors uploaded?: No. Parsing, conversion, preview, and copying run locally in the browser.

Color conversion and readability

Changing format does not guarantee contrast. Before using a color for text, buttons, or links, test it against the real background for WCAG contrast, brand fit, and UI states.

How to choose a CSS color format

The same color can be written as HEX, RGB, HSL, or HSV, but each format fits a different maintenance job.

Use HEX for compact design handoff values and stable theme tokens.
Use CSS rgb() or hsl() when you need alpha, variables, or dynamic composition.
Use HSL when creating hover, active, lighter, or darker variants because hue, saturation, and lightness are easier to reason about than raw RGB.

Accessibility checks before shipping colors

Color conversion keeps values equivalent, but it does not prove text readability, state clarity, or contrast compliance.

Check body text and button text against the real background with WCAG contrast rules.
Do not communicate error, success, or disabled states by color alone; include text, icons, or shape changes.
When using brand colors for links or focus rings, verify hover, active, disabled, and selected states too.
