When to use
Preparing digital designs for professional print production.
Converting web-based color palettes to CMYK color spaces.
Managing transparency in colors when transitioning from screen to print.
How it works
1Input your HSL color values in various formats like hsl(0,100%,50%) or raw H,S,L values.
2Select your preferred output format, such as standard CMYK percentages or labeled strings.
3Choose how to handle alpha channels by compositing them against a white, black, or custom background color.
4Generate the converted CMYK values instantly for use in your design software.
Use cases
Converting brand color palettes from web CSS to print-ready CMYK values.
Adjusting semi-transparent UI elements for inclusion in printed marketing brochures.
Standardizing color values across digital and physical media assets.
Examples
1. Converting Brand Colors for Print
Graphic Designer
Background
A designer has a brand color defined in HSL for a website and needs to use it on a business card.
Problem
The printer requires CMYK values, but the designer only has the HSL code.
How to use
Paste the HSL value into the input field and select the 'cmyk' output format.
format: cmyk, alphaHandling: white
Outcome
The tool provides the exact CMYK percentages needed for the print file.
2. Handling Transparent Overlays
Print Production Specialist
Background
A project includes a semi-transparent overlay that needs to be printed on a white background.
Problem
The alpha channel needs to be flattened to a solid color to be compatible with CMYK printing.
How to use
Input the HSLA value and set the Alpha Channel Handling to 'Composite with white background'.
FAQ
Why do I need to convert HSL to CMYK?
HSL is designed for screens (RGB), while CMYK is the standard for physical printing. Converting ensures your colors appear as intended on paper.
How does the tool handle transparency?
Since CMYK does not support transparency, the tool composites the color against a background of your choice (white, black, or custom) to create a solid printable color.
Can I process multiple colors at once?
Yes, you can paste multiple HSL values into the input area, each on a new line, to convert them in a single batch.
What is the recommended background for printing?
Compositing with a white background is generally recommended for printing as it mimics the standard white paper substrate.
Are the CMYK values accurate?
The tool uses standard color space conversion algorithms to provide precise CMYK equivalents based on your input.
