ISC License
ColorCheat does simple color transformations by way of a mapping file. It lets you define your color transformations in a program like Photoshop or Gimp, and apply those transformations to new images by way of an RGB map.
Generate a fresh RGB map file:
$ python make-image.py map.png
Open map.png
in Photoshop, and apply your color transformations as
adjustment layers:
Save map.png.
Apply the transformation to a new image:
$ python apply-image.py photo.jpg map.png result.jpg
