Setting the color of own nickname

That’s interesting. I’d come across a lower-entropy but more human-readable image hash for avatars, designed by a dev-artist:

DC Desktop default chat avatar colors

How about making the default avatars a hash of the key or key fingerprint, not the username? Even the most ignorant user would then rightly suspect, when the avatar changed, that they were talking to a different person. Separately, another programmer-artist made a program to hash forum usernames to pictures of cartoon cats, subsequently extended to hash usernames to birds (also in Rust), and to hash usernames to foxes, squid, and abstract art. These seem to have about 15 bits of entropy. Not en…

I’d think it would be possible to generate something higher-entropy but more engaging to humans.
