TY. Each byte is encoded into a blinking sequence of 3 colors and there are 8 total different colors. More permutations than are needed because I wanted to also avoid repeating the same color twice in the sequences.

I saw it originally here: bsky.app/profile/pixe...

Thanks for sharing, this post inspired me to write some scripts to do something similar. Though I went with blue, and the first book I encoded is a book about sandwiches. github.com/FoamyGuy/Boo...
