How to Export a Color Palette as CSS Variables

Generate and export a color palette as CSS custom properties ready to paste into your stylesheet.. This step-by-step guide walks you through the process using LevnTools Palette Generator, a free browser-based tool that handles everything locally on your device. No software to install, no account to create, and no files uploaded to external servers. Follow these steps to complete the task in under a minute — updated for 2026.

Create or select your palette

Build a color palette by selecting a base color and harmony rule, or manually pick each color. You can also import an existing palette by entering HEX codes.

Name your colors

Assign semantic names to each color in the palette (e.g., primary, secondary, accent, background, text). These names become the CSS variable names in the export.

Export as CSS variables

Click the Export button and select "CSS Custom Properties" format. The tool generates a :root block with --color-primary, --color-secondary, and other named variables.

Copy and paste into your stylesheet

Copy the generated CSS code and paste it into the :root section of your stylesheet. Reference colors throughout your CSS using var(--color-primary) syntax.

Pro Tips

Use descriptive variable names like --color-primary and --color-danger rather than color-specific names like --color-blue.
Include shade variations (--color-primary-light, --color-primary-dark) for more flexibility.
CSS custom properties are supported in all modern browsers. No preprocessor needed.

Common Issues & Fixes

Issue: CSS variables are not working in my project.

Fix: Make sure the variables are defined in the :root selector and that you are using the var() function to reference them. Check for typos in variable names.

Issue: The exported variable names have spaces or special characters.

Fix: CSS custom property names must use hyphens instead of spaces. The tool should handle this automatically, but verify the output names are valid CSS identifiers.
