Found a few more bytes to play with. I used to make all kinds of scrollers on the c64 in the 80's and 90's, so this is a lot of fun for me.

Interesting method of #color selection
u/taupelink

Yeah, the substring color technique is not new. I first saw it at https://www.dwitter.net/d/14621
u/DataMeta

What is new is getting a nice palette of secondary/intermediate colors with it
