Experimenting with changing color palette of an image:

The technique: I converted the image into 5 color palette using the imageMode tool in GIMP(~photoshop) and the used the alien filter to change the palette until I found something interesting.

I made the following compositions with this palette in Processing – original image files and source code on github:

I really enjoyed changing the palette of the leaf image above, so I made a tool in p5.js to convert any image into my palette. (code on github and alpha editor) Here are some interesting compositions that resulted from playing around with this code:
