What exactly does the output look like?

A colon-root block with one custom property per color, indented for readability, each value an uppercase six-digit hex, and a copy button for the whole block.

Can I rename the properties?

The tool emits numbered names because it does not know each color's role. Take the block as a starting point and rename the declarations to the roles they serve.

Does it generate light and dark themes?

No. It produces one flat set of declarations. Wrapping them in media queries or theme selectors is a project-level decision left to you.

Why use variables instead of the hex values directly?

A color written once can be changed once. Variables also make theme swapping and runtime theming practical, because every consumer follows the declaration.

Can I generate light and dark variants in one go?

No. The block declares a single set of properties; theme variants, media queries and alpha handling are decisions about how a project structures themes, so those wrappers are added around the exported declarations.

The color palette CSS exporter turns an editable palette into a ready-to-paste :root block of numbered custom properties, one declaration per color.

What is Color Palette CSS Exporter?

The color palette CSS exporter edits a palette and writes the CSS custom properties for it. You keep a list of colors — add, remove, or adjust any of them — and the output beside it is a :root block containing one declaration per color, numbered from one, with the hex value uppercased. A copy button lifts the whole block onto the clipboard. It is the shortest route from a set of colors you have chosen to a stylesheet that can reference them by name, turning a palette to css variables with no hand editing at all.

The output shape is deliberately plain:

A :root block with one declaration per colour, numbered from one.
Each declaration indented two spaces for readability in a diff, with property names following the numbered pattern --brand-1, --brand-2 and upward.
Every value a six-digit hex, with no comments, no fallbacks and no nested theme blocks, so the block pastes directly into a stylesheet, a CSS-in-JS template or a build step that concatenates stylesheets.

The reason to put colors in custom properties rather than writing the values inline is maintenance. A literal repeated in twelve places has to be found and changed twelve times, and the risk is that one gets missed and the interface develops a slightly-off shade that nobody can quite explain. A variable changes once. That matters most when a theme swaps: if every surface and accent reads from a property, switching palettes is a matter of redefining the block rather than rewriting rules. It is also what makes runtime theming on a website practical at all.

Naming is the one thing the tool cannot decide for you. It emits numbered names because it has no idea what the colors are for, and numbered names are a poor long-term choice: a property called brand dash three tells a future reader nothing about whether it is a border or a call to action. The sensible workflow is to take the generated block as a starting point and rename each declaration to the role it serves, because role-based names survive a rebrand while appearance-based ones do not.

Because the palette editor is live, iterating is cheap: adjust a color and the declaration updates immediately, so you can paste, preview and paste again. That makes it useful early in a project, when the palette is still moving, and later when a single shade needs nudging. If the target is not plain CSS but a framework config, the design token generator produces a structured object instead, and if the goal is JSON data rather than stylesheet declarations, the JSON exporter covers that direction.

A few things are intentionally out of scope:

The block declares a single set of properties, with no light-and-dark variants, no media queries and no alpha handling.
Property names are numbered rather than role-based, because the tool has no idea what the colors are for, so renaming each declaration to the role it serves happens in the stylesheet and is what makes the names survive a rebrand.
Theme architecture is yours to wrap around the leaf declarations.

Nothing more is claimed for it than that: it is a css color variables generator rather than a theme architecture, and when the requirement is simply to export palette as css declarations that paste cleanly, that narrowness is exactly the feature.

How to use Color Palette CSS Exporter

Edit the palette in the left-hand card until the values are right.
Read the :root block beside it — each change updates the declarations immediately.
Copy the block into a stylesheet, a CSS-in-JS template or a build step.
Rename the numbered properties to the roles they serve before committing.

When to use Color Palette CSS Exporter vs related tools

Use this exporter when you want a palette as a paste-ready block of CSS custom properties. Use the design token generator when the target is a token object, and the JSON exporter when you need data rather than declarations. When the target is a token object rather than declarations the design token generator produces the structured shape, and for data rather than a stylesheet the JSON exporter is the match.
