Color Converter.

Convert color codes between HEX, RGB, HSL and CMYK formats instantly. Pick a color visually or type any value — ideal for designers and developers.

This tool converts color codes between HEX, RGB, HSL and CMYK formats in real time. Whether you are building a website, designing a logo, or matching brand colors, just pick a color or enter any value and all four formats update instantly. Everything runs in your browser — no data is ever sent to a server.

How to use

Click the color swatch at the top to open your device's color picker, or type a HEX code directly into the HEX field (the # is optional). You can also adjust the R, G, B numbers for RGB, or the H, S, L numbers for HSL — all fields stay in sync. CMYK updates automatically and is read-only since it is derived from RGB. Click the Copy button next to any format to copy the CSS-ready value to your clipboard.

Color conversion works best when one color can travel cleanly between tools

A useful color converter is not really about generating more codes. It is about keeping one visual choice intact while it moves between design files, CSS, component libraries, and print references. The same color may need HEX for a handoff, RGB for implementation, HSL for adjustment, and CMYK for a print-adjacent document.

This tool keeps those formats aligned in one place so you can move between them without losing track of the original color.

Where the friction usually appears

Design-to-development handoff

One person speaks in design tokens or HEX, another needs CSS values, and a copied number with one wrong character is enough to produce the wrong shade in production.

Brand work

A brand color is not only a visual idea. It is a set of exact numeric representations that need to stay aligned across assets, code, and documentation.

Troubleshooting existing UI

When something looks slightly off, checking the same color across multiple formats can reveal whether the issue is the code, the conversion, or the source value itself.

The mistakes that matter

Assuming equivalent-looking values are interchangeable

Two values can look close and still not be the same color. That matters more when a brand system depends on consistency.

Treating CMYK as identical to screen color

CMYK is useful as a reference, but screen and print workflows are not perfect mirrors of each other. The conversion helps you translate, not guarantee identical physical output.

Editing one format and forgetting the others

The benefit of a synchronized converter is that you can adjust one representation and immediately keep the rest aligned.

Practical examples

Turning a picked color into production code

You may find the right shade visually first and only afterwards need the exact HEX or HSL value for implementation.

Verifying a style guide

If a document lists HEX, RGB, and CMYK for the same brand color, a converter makes it easier to check that those values still describe the same intended result.

Debugging an off-brand interface element

When a button or background looks wrong, comparing linked outputs can help isolate whether the issue is a bad pasted value or a misunderstanding about format.

What this tool does not do

This tool converts color formats. It does not assess accessibility contrast, build a full palette, or replace calibrated print proofing. It is for accurate representation transfer, not for every design decision around color.

The useful discipline behind it

The goal is not simply to generate more codes. It is to keep one color identity coherent while it moves through different parts of a workflow. That is where converters save real time and prevent low-grade design inconsistency.

Examples

Pure red #ff0000 → rgb(255, 0, 0) → hsl(0, 100%, 50%)
Sky blue #87ceeb → rgb(135, 206, 235) → hsl(197, 71%, 73%)
Forest green #228b22 → rgb(34, 139, 34) → hsl(120, 61%, 34%)
White #ffffff → rgb(255, 255, 255) → CMYK C:0% M:0% Y:0% K:0%
Black #000000 → rgb(0, 0, 0) → CMYK C:0% M:0% Y:0% K:100%

FAQ

What is a HEX color code?

A HEX code is a six-character string used in web design and CSS to define colors. It starts with # followed by three pairs of hexadecimal digits representing red, green, and blue values — for example, #ff0000 is pure red.

What is the difference between RGB and CMYK?

RGB (Red, Green, Blue) is an additive color model used for screens — it mixes light. CMYK (Cyan, Magenta, Yellow, Key/Black) is a subtractive model used in printing. The CMYK values shown here are a device-independent approximation from the RGB values.

Why do my CMYK values differ from my printing software?

Professional printing software uses ICC color profiles which vary by printer and paper. This tool calculates a standard mathematical approximation, which is great for web use but may differ from print-specific profiles.

Is this tool free and private?

Yes — completely free and runs entirely in your browser. No color values are sent to any server.
