I'm sorry, but I don't quite understand the answer that Mod T gave for the answer about blood colors. Do the fantrolls mean that there can be in-betweens or not? Because i feel like i read that mierfa has cerulean-colored blood, the same adjective as vriska. I'm sorry im not trying to be contrary or anything i really dont understand that answer

Neither of the canon fantrolls share the same exact color of blood as any of  the other trolls.  Yes it may be cerulean but it’s not the same shade.  Any tint, hue, or shade off the ordinary hemospectrum is fine and totes canon.
