I recently put together a visualization that takes the first 100 pages of various comic books and shows the colors used by them.
For example here is Saga:
And here is Pretty Deadly:
It’s really interesting to compare how different artists use colors, and how colors plays a role in the stories told by comic books.
I used a combination of Processing and P5.js to put the visualization together. Here is a discussion on the process, and here is the code I used.
Really interesting process, and very well done!
Why is there white line between the colors? Can you comment on your approach, for instance, if somebody wants to reproduce your results?
Maybe somebody could do a frequency study of music/sounds this way. Next time somebody is looking for a topic, I will bring this one forward.

It’s not that there are white lines between the colors. It’s that white is one of the colors used by many pages. Each page was converted into 4 representative colors, and many pages contain a good amount of white.
If you want more info, check out the two links at the bottom of my first post. This includes my process and the code I used. 
Very interesting! I like your way to apply k-means to all colors on a page to come up with something else than just an average.
