Demos

Generate Dark Theme

$ colorstorm

This command will generate a random editable dark color theme. Re-running the command will result in a different theme each time.

Generate Light Theme

$ colorstorm -l

This command will generate a random editable light color theme. Re-running the command will result in a different theme each time.

Generate Monochromatic Theme

$ colorstorm -m

This command will generate a random monochromatic color theme. Re-running the command will result in a different theme each time.

Using a Reference Image

You can pass a reference image to colorstorm, which will convert it into a set of colored ASCII half-block characters and render it above the theme editor.

When an image is provided, you can toggle between viewing the image and the list of colors in the image using the ~ key.

Demo Image:

$ colorstorm -i <path to image>

Using the Color Picker

When passing a reference image to colorstorm, you can use the built-in color picker to select colors directly from the image to use in your theme.

When a theme field is focused (i.e. Background, Foreground, etc), press p to enable the color picker. A white crosshair will appear on the image, and you can use the arrow keys to move the crosshair around the image. The focused color will update with whatever color is under the cursor in real time.

Demo Image:

$ colorstorm -i <path to image>
