Advanced Color Converter & Tailwind Picker

Convert colors instantly between HEX, RGB, HSL, and CMYK formats. Whether you are designing for the web (sRGB) or preparing files for print (CMYK), this tool provides accurate values and color previews.

Web Developers: Stop guessing class names. Our tool automatically finds the Closest Tailwind CSS Color to your input, saving you time when migrating designs to code.

Tailwind Matcher

Paste any random HEX code, and we will tell you if it matches a standard Tailwind class like bg-blue-500. If not, we find the nearest visual match.

Print Ready (CMYK)

Designers need CMYK (Cyan, Magenta, Yellow, Key) for physical printing. We accurately convert your screen colors to printer-safe percentages.

EyeDropper API

On supported browsers (Chrome/Edge), use the built-in EyeDropper tool to pick any pixel from your screen even outside the browser window and get its code instantly.

Understanding Color Models

RGB (Screen)

Red, Green, Blue. An additive color model used for digital screens. Light is added together to create white. Use this for CSS, HTML, and App design.

HEX (Web Standard)

A hexadecimal representation of RGB. It uses 6 digits (0-F) to define the red, green, and blue values. Example: #FF5733.

CMYK (Print)

Cyan, Magenta, Yellow, Key (Black). A subtractive model used for ink. Ink absorbs light. Converting RGB to CMYK often makes colors look "duller" because ink cannot be as bright as a screen.

HSL (Human)

Hue, Saturation, Lightness. The most intuitive format. Want a lighter blue? Just increase the "L" value. Perfect for creating color palettes programmatically.

Frequently Asked Questions

Why do my colors look different when printed?

Screens emit light (RGB), allowing for neon and very bright colors. Printers use ink (CMYK), which reflects light. Many bright screen colors are "out of gamut" for standard printers and will be automatically dulled down.

How do I use the EyeDropper?

Click the pipette icon on the main color preview. Your cursor will turn into a magnifying glass. Click anywhere on your screen (even desktop apps) to capture that pixel's exact color code. *Note: Only works on Chromium browsers (Chrome, Edge).*
