The Complete Color Converter for Developers and Designers

Every developer hits the same wall: your design system uses HSL, Tailwind uses HEX, the brand guide uses RGB, and the print team wants CMYK. Switching between a browser DevTools color picker, a separate contrast checker, a palette generator, and a CSS variables snippet wastes minutes on a task that should take seconds.

This tool gives you every color format in one place. Paste a #HEX, enter rgb() values, or click the native color picker — and instantly see HEX, RGB, HSL, HSV, CMYK, a Tailwind-style 10-shade palette, WCAG contrast ratios, color harmony suggestions, and a ready-to-paste CSS variables block. Everything runs in your browser: no uploads, no API keys, no account.

How it works

Pick, Convert, Copy — in One Page

Pick or paste a color

Click "Pick color" to open the native browser color picker, or type a HEX value directly. You can also enter RGB or HSL numbers manually.

See all formats

HEX, RGB, HSL, HSV, and CMYK update in real-time as you adjust any field. Click any format's copy button to grab the value.

Check contrast and accessibility

WCAG AA and AAA badges tell you instantly whether your color passes accessibility guidelines for normal and large text.

Explore shades and harmony

Browse a 10-step Tailwind-style shade palette and four color harmony schemes. Click any swatch to select it as your active color.

FAQ

Frequently Asked Questions

1How do I convert a HEX color to RGB?

Type or paste your HEX value into the HEX field — RGB values appear instantly below. You can also click the copy button next to the RGB field to copy the rgb() CSS value.

2What is WCAG contrast ratio and why does it matter?

WCAG contrast ratio measures text readability against a background. A ratio of 4.5:1 passes WCAG AA for normal text, and 7:1 passes AAA. Use this to ensure your color choices are accessible to users with low vision.

3What is the difference between HSL and HSV?

Both use Hue and Saturation, but differ in the third channel. HSL uses Lightness (100% = white, 0% = black). HSV uses Value/Brightness (100% = brightest hue, 0% = black). CSS uses HSL; graphics tools like Photoshop often use HSV.

4Can I use this tool offline?

Once the page has loaded, all conversions and calculations run entirely in your browser. No network requests are made after the initial page load.
