A Python utility to create color palettes based off of an image. Uses k-means clustering to generate an RGB shades palette based off of the predominant colors of the source image. User can customize the number of colors in the generated palette.

Tested for Python 3.7, but should work for Python 3.2+

Download/clone somewhere on your computer and download the requirements in the Pipfile. Put the source image in the same directory and then run the program with python. Run it with the following command line arguments:

usage: palette.py [-h] [-s [image source]] [-n [number of colors]]

Generate a color palette based on a source image.

optional arguments:
  -h, --help            show this help message and exit
  -s [image source], --src [image source]
                        Path to the source image (default: None)
  -n [number of colors], --number [number of colors]
                        Number of colors in the palette (default: 8)

If an image source isn't provided in a command line argument, the program will ask you for one upon invocation.

Using values of n greater than ~16 will produce mediocre results. The suggested (and default) value is 8, but play around with the number depending on your source image.

In a few seconds it will display the palette, which you can then save wherever.
