A command-line tool for extracting dominant colors from an image.
I use this program to extract the most saturated color from my randomly changing desktop wallpaper to sync my LED lights with.
$ git clone https://github.com/tupakkatapa/color-extractor.git
$ cd color-extractor
$ pip3 install -e .$ color-extractor [path to image file] [options]Important note: The order of the options [--number], [--sort], and [--mod] provided matters. Multiple instances of these options can be used and the actions will be performed in the order they were provided. If the number of wanted colors (--number) is not specified but other actions are (--sort or --mod), the limiting to the desired number of colors will always be performed last.
$ color-extractor --help
usage: color_extractor.py [-h] [-f] [-o [OUTPUT_PATH]] [--format {hex,rgb,hsv}] [--include-hashtag]
[-c [NUM_CLUSTERS]] [-n NUM_COLORS] [-s {saturation,value,brightness,chroma}]
[-r] [-m {max-val,max-sat}] [-v] [FILE]

The order of the options [--number], [--sort], and [--mod] provided mattersand these options can have many instances.
positional arguments:
FILE Required. The path to the image file.
options:
-h, --help show this help message and exit
-f, --force Overwrite output file if it already exists. Default = False
-o [OUTPUT_PATH], --output [OUTPUT_PATH]
The output of the result will be saved to this file.
--format {hex,rgb,hsv}
Output color format. Default = 'hex'
--include-hashtag Include '#' before hex color in output. Default = False
-c [NUM_CLUSTERS], --clusters [NUM_CLUSTERS]
The number of color clusters to pick colors from. Default = 20
-n NUM_COLORS, --number NUM_COLORS
The number of colors to output. Default = 5
-s {saturation,value,brightness,chroma}, --sort {saturation,value,brightness,chroma}
The criteria to sort the colors by. Default = 'frequency'
-r, --reverse Reverse the sort order. Default = False
-m {max-val,max-sat}, --mod {max-val,max-sat}
Modify the color properties. 'max-val' maximizes the value/brightness of the color(s)
and 'max-sat' maximizes the saturations of the color(s). Default = None
-v, --verbose Increase output verbosity.- Find (20) color clusters from an image, sort them by frequency, pick the top 5 and print them to the console:
$ color-extractor image.jpg- Find (20) color clusters from an image, pick the top 10, sort them by saturation and write the output to a file:
$ color-extractor image.jpg -n 10 -s brightness -o output.txt- Find 30 color clusters from an image, sort them by saturation, pick the top one, maximize value and saturation and write the output to a file in the cache directory:
$ color-extractor ~/pictures/wallpapers/image.jpg -c 30 -s saturation -n 1 -m max-val max-sat -o ~/.cache/color
