Accepted input formats
The Color Code Converter accepts any standard input for this utility type.

Unicode strings, multi-byte characters, special symbols, and multi-line blocks are fully supported.

How the Color Code Converter works
Pick a tab — HEX, RGB, or HSL — matching the format of the color you have.
Enter the value: a HEX code like #FF5733, or numeric R/G/B or H/S/L fields.
The other two formats and the swatch update automatically as you type.
Read the HEX, RGB, and HSL values from the output line below the swatch.
Tips & tricks
- Switch tabs to match your input format — the fields under each tab are independent, not a single universal input.
- The swatch updates live, so you can visually sanity-check a converted value before copying it.
- HSL is often easier for tweaking a color's brightness or intensity — raise L to lighten, lower S to mute it.
- There's no alpha/opacity channel — for CSS with transparency, add the alpha value manually after converting (e.g. rgba(r, g, b, 0.5)).

Frequently Asked Questions
What CSS color formats does this tool support?
This tool converts between HEX (3- or 6-digit), RGB, and HSL — the three most common CSS color formats. It doesn't currently support RGBA/HSLA alpha channels, HSB/HSV, CMYK, or named CSS colors like "coral".
What is the difference between RGB and HSL?
RGB defines a color by its red, green, and blue light components (0–255 each). HSL defines it by hue (0–360°), saturation (0–100%), and lightness (0–100%) — often more intuitive for adjusting a color, since you can lighten or desaturate without recalculating RGB.
How do I convert a named CSS color like "coral" to HEX?
This tool doesn't look up named colors — enter its HEX value directly instead (coral = #FF7F50). You can find a named color's HEX value in the CSS Color Module spec or any browser's color picker.
What is HSB/HSV and does this tool support it?
HSB (Hue, Saturation, Brightness), also called HSV, is used in Photoshop and many design tools — it's similar to HSL but defines the third channel differently. This tool converts HEX/RGB/HSL only; if your source is HSB, convert it in your design tool first.
Can I convert colors with CSS custom properties (variables)?
Enter the actual color value, not the variable name. Resolve --my-color to its value first, then convert. The tool works with actual color values, not CSS variable references.
What formats does the Color Code Converter support?
The Color Code Converter converts between hex, rgb, hsl. All conversions work in both directions — instantly, with no sign-up required.
Is my data safe when using the Color Code Converter?
Completely safe. The Color Code Converter processes everything locally in your browser. No input data, results, or usage information is ever transmitted to or stored on any server.
Can I use the Color Code Converter output in commercial projects?
Yes. The Color Code Converter is a utility tool and its output carries no licensing restrictions. You are free to use results in any project, commercial or personal.
Does the Color Code Converter follow official standards?
Yes. The Color Code Converter is built to comply with the relevant industry standard or specification for this utility type. If you encounter an unexpected result, verify your input against the specification — edge cases outside the standard may produce undefined behaviour.
