Many (most?) moderators use colour in their role PMs and flips in order to make it clearer at a glance what faction a player belongs to. However, I'm interested in what the most common colour scheme for this is, and if particular factions tend to always be associated with particular colours. (Also, if anyone uses colour for features other than faction/win condition, I'd be interested in that too!)
The only other colour that I'm fairly confident in is that
But what about all the other possible factions/wincons? Do they have colours of their own? If not, what colour should be used for, e.g., the setup summaries on the wiki? I feel like Serial Killer is definitely used often enough to be standardised/standardisable, and Jester might be.
A full list of the factions that need colours: Town, Mafia, Serial Killer, Werewolf, Survivor, Unjester, Jester, Mime, Lyncher, Unlyncher, Cult, Inquisitor, Mentor, Arsonist. My current provisional assignment is shown on the wiki as Template:FactionColor, but you might well have better ideas on how to colour things than I do. Ideally, the colours would be at least visible on every skin, and would not mislead players about how their win condition worked.
