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'm really impressed with how well it retained the fuzziness of their faces and on the traces on the upper one's wing segments.
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
