It would be nice if there were a less trivial mapping of IP address to color -- something where ASN boundaries mattered, and maybe where netmask got taken into account. (so a bunch of users on /29s and /30s within the same IP block got related but different (and ideally distinguishable) colors.

It would still be a canonical IP to color mapping, but it wouldn't be as literal a mapping of 32-bit address into 32-bit color.
