Pac-color is a tiny web-app that dynamically generates solid-color images as well as getting JSON representation of color conversions to other formats.

We at pacstall use this tool to generate swatches for release notes (https://github.com/pacstall/pacstall/releases).

The most common usage is to get a color swatch, which can be done like this:

wget https://colors.pacstall.dev/E09540/preview

Which will download the swatch with the color #E09540.

You can also optionally change the size with size query parameter in the form: ${height}x${weight}, such as 16x16.

Finally, you can change the default generated filetype with the type query parameter. Currently, we accept the following:

• png
• jpg
• gif
• ico
• webp
• tiff
• svg

If you remove /preview from the slug, you will get a neatly formatted JSON response containing various color conversions.
