[@UnknownScarlet4] I suppose that depends on definition of mutant blood? While there is not much in cannon to support this theory when they use the phrase 'hemospectrum' I really picture the use of spectrum as it applies to color in general, meaning a wider verity than what we see in comic. If this isn't a view held/shared bout our GMs or the group at large I'll be willing to bump him down to traditional sea dweller color.
