Main Colors of Original 151 Pokémon [OC]

This is a collection of 151 hexagonal pie charts arranged in columns, top to bottom, left to right, representing the proportions of the top 3 dominant colors of each of the original 151 Pokémon.
* I began with the official Sugimori art found on the veekun archive
* I stripped out transparent backgrounds and “dark colors”, computed by transforming RGB to Adobe Luma
* I converted RGB to CIE LAB, a “perceptually uniform” color space, so that Euclidean distance would correspond to human perceptual color difference
* I ran k-means clustering with 3 clusters and extracted the cluster centers, then associated each pixel back to a cluster to get proportional weights
* I used an SVG library to manually draw each pie chart alongside mathematics for rotations, trigonometry, hexagonal geometry, clip paths, randomizing the starting angle of the pie chart, a coordinate system, etc.
* Figuring out a nice way of representing 151 hexagons was the most manual part; I ended up settling on a hexagonal grid of size 8 with 169 hexagons, which means I only had to remove 18 = 6 x 3 = 3 per side. I removed the corners, and then removed 2 more from each side in a symmetric way, and ended up with this snowflake pattern

It’s interesting to see clusters of 2-3 similarly colored hexagons representing the evolutions, as well as to compare to the original images to see what the algorithm picked up.

I’ll link a GitHub with these methods in a general purpose Python library if people are interested.
