HERE ARE MY HOLMESTUCK HEADCANONS!!!
A lot of this is taken from other people’s lists, but quite a bit was made up/modified by me, like the server-client order and some of the chumhandles.
DISCLAIMER: I am in no way saying that these should be the headcanons/rules for everyone’s version of Holmestuck, because that’s fucking ridiculous. These are just the guidelines that I’ll be using in my own dumb page edits, pesterlogs, etc!
But if you want to use this as a reference for your own stuff, please feel free!
edit: added swatches for color references!
