Butterflies - This image only has 16 colors
(thelemmy.club)
This is a 16 color palette reduced image using my own custom palette generator algorithm. The palette it detected and in use is in the top right.
Based on this post right here...
I didn't exactly reinvent the error diffusion dithering algorithm, I just reinvented palette reduction tailored to a specific image, that gives the most optimal palette for the given image.
I wrote the algorithm like 18 years ago, kinda just testing myself to see if I even remember how it works in its incomplete state. Apparently so.. ๐
