Install

pip install colorgen

Or from source:

git clone https://codeberg.org/piotrkrzysztof/colorgen.git
cd colorgen
make install

Requires Python 3.12+.

Usage

# Preview colors from an image
colorgen wallpaper.png --preview

# Generate and apply a kitty colorscheme
colorgen wallpaper.png --config kitty --theme dark --apply

# Multiple targets
colorgen wallpaper.png --config kitty awesome rofi --apply

# All targets
colorgen wallpaper.png --full-config --theme dark --apply

When applying, the old theme gets commented out, not deleted.

How it works

Extracts 10 dominant colors from the image via K-means clustering, then maps them to a 19-color terminal palette (bg, fg, cursor, colors 0-15) based on hue diversity and luminance.

Supported targets

• kitty - terminal color config
• AwesomeWM - window manager theme (awesomewm-basileia layout)
• Waybar - status bar colors via @define-color CSS variables
• dunst - notification daemon colors via dunstrc.d drop-in
• rofi - launcher theme (adi1090x/rofi layout)
