DESCRIPTION

PyPalEx is a tool for extracting color palettes from images and generating a JSON format file with light, normal, and dark color schemes/palettes. This tool is intended to be non-OS dependant, for use by the tech community for developing their own custom theme managers or by artists who want to generate color palettes for thier art from images/pictures/wallpapers they adore.

PyPalEx does NOT select only dominant colors from an image. Instead, it picks out the most prominant light, normal, and dark color for each of the base colors (red, yellow, green, cyan, blue, magenta) in an image and constructs a color palette for each of these three variants. When a specific color is not present in an image, that color is borrowed from one of the colors that is present. (e.g. Colors red and cyan are missing from an image, so red and cyan are borrowed from the colors that are present in the image.)

NOTE

Future update may include a -p --pastel option for generating pastelle palettes as well as a -g --generate option for generating missing colors from their respective hue range instead of borrowing missing colors from pre-existing colors in the image.

INSTALLATION

DEPENDENCIES

• Python 3.7+
• Pillow (PIL) 9.0+
  • For performing operations on images.
• NumPy 1.21+
  • To manage large amounts of image data.
• filetype 1.0+
  • To confirm filetypes are images file types.

Aside from Python, the rest are python packages/libraries that are installable with pip.

ENVIRONMENT VARIABLES

Two shell environement variables PYPALEX_CACHE_DIR and PYPALEX_CONFIG_DIR can be set in terminal. PyPalEx, by default, will either store generated palettes into PYPALEX_CONFIG_DIR OR wherever (XDG_CONFIG_HOME/palex or $HOME/.config/palex) points to.
This default storing location is, of course, overriden if pypalex is used with the -o --Output option.
