What are you able to vary besides fill-colour, e.g. font, size etc?
A blind-spot which prompts to ask.
Vary too much and it becomes a useless fuzzy heiroglyph.
Color-blindness must remain a priority.
One thing is obvious - font should be white.
To that end I'd make every 3rd character determine the colour for a block of 3. More visually mnemonic. Can it be spread across multiple lines? e.g. 3 lines of 11 characters
Yes much easier on the eyes especially when viewed in a list of others ;)
Precisely the sort of thought I hoped to read.
I will generate a few examples of what I have now for demonstration.
Expanded to Base64,
I am looking at this at the moment
