About Color Formats
HEX (Hexadecimal)
The most common color format for web design. A 6-digit code prefixed with # representing RGB values in base-16. Example: #FF5733.
RGB (Red, Green, Blue)
Colors defined by three values (0-255) representing red, green, and blue light intensity. Used in CSS: rgb(255, 87, 51). Also supports alpha transparency with RGBA.
HSL (Hue, Saturation, Lightness)
An intuitive color model: Hue (0-360° on the color wheel), Saturation (0-100%, color intensity), and Lightness (0-100%, brightness). Often easier for designers to adjust than RGB.
CMYK (Cyan, Magenta, Yellow, Key/Black)
Used primarily for print design. Values range from 0-100% for each ink color. Note: RGB to CMYK conversion is approximate as they target different mediums (screen vs print).
Frequently Asked Questions
Is this tool free?
Yes. Completely free, no registration, no limits.
Can I use the converted colors in CSS?
Yes. Copy the HEX, RGB, or HSL values directly into your CSS. All formats are standard and supported by all modern browsers.
How accurate is the RGB to CMYK conversion?
The conversion is mathematically accurate but approximate. Screen colors (RGB) and print colors (CMYK) have different gamuts — some bright screen colors cannot be exactly reproduced in print.
