Coding Challenge: Use Colour Classifier NN you made recently for Image Compression

I know that as a compression method it will most likely destroy up to 95% of the detail of an image but for some trippy art and as a proof of concept, one could assign a general "...-ish" RGB value to the NN output and then looping over all the pixels it will classify the colour and replace it with "...-ish"

i.e. you set "blue-ish" as 0,0,255 and then any pixel colour that gets classified as "blue-ish" gets replaced with 0,0,255.

Then converting the original and final images to JPEG in order to see how big of a difference there is in terms of file size
