I realised only Gamzee and Kurloz have matching colours for both their blood colour and Rage colour schemes. It's as if Rage was destined to Capricorns or vice versa.

Hussie did mention that he tried to make the Aspects unrelated to the characters, except for Rage, which he made to look like a weird angry clown face because, it was just too fitting and fun not to do it like that.
