How It Works
This tool converts a color between HEX, RGB, HSL, and CMYK simultaneously, with a visual picker — useful whenever a design tool or codebase needs a color in a specific format different from the one you have.
What each format is actually for
HEX (#RRGGBB) and RGB (red, green, blue values 0-255) are the two most common formats in web design and CSS. HSL (hue, saturation, lightness) is a more human-intuitive way to describe color — easier to reason about "a bit lighter" or "more saturated" than adjusting raw RGB values. CMYK (cyan, magenta, yellow, key/black) is used specifically for print — printers mix physical ink rather than emitting light, so print design software works in CMYK, not RGB-based formats.
Why RGB-to-CMYK conversion is approximate
RGB describes light (as emitted by a screen) while CMYK describes ink (as absorbed on paper) — these are different color models covering different physical ranges, so converting between them is always an approximation rather than an exact one-to-one mapping. For color-critical print work, always confirm final CMYK values with your printer rather than relying solely on a screen-based conversion.
Examples
Getting a CSS-ready HEX code
Picking a color visually and reading off its HEX value (e.g. #3B82F6) for direct use in a CSS stylesheet or design tool.
Preparing a color for print
Converting a brand's RGB/HEX color to its approximate CMYK equivalent before sending a print design file to a printer, understanding the final printed color may need minor adjustment.
Common Use Cases
- Converting a design tool's color format to whatever format a codebase or CSS file requires
- Getting an approximate CMYK equivalent before sending a design to print
- Understanding or adjusting a color using HSL's more intuitive hue/saturation/lightness sliders
Tips
- For anything web/screen-based (websites, apps, digital designs), stick to HEX or RGB — CMYK is only relevant once you're specifically preparing something for physical printing.
- If exact color matching for print is important (e.g. matching a specific brand color), get a Pantone or CMYK value directly from your brand guidelines rather than relying purely on an RGB-to-CMYK conversion, since the conversion is approximate.
