(  …Karkat only has one blood color. The cycling of colors you saw at first was just Hussie keeping it a mystery. (ditto for the bleeding question marks. Karkat is an off-spectrum mutant who has blood that’s colored the same as a human, as opposed to Aradia, who’s red is darker than a humans)  )

(The thing with Karkat having rainbow blood was just a way to keep it a mystery for the reader. He actually has red blood. )

( I hate to break it to you because you really seem to be enjoying the karkat vampire theory, but the gif where karkats blood is rainbow was just meant to represent us not knowing what the actual color is. His blood is actually that bright red color. )

( The Rainbow flashing of Karkat’s blood was just a viewer abstraction so that we couldn’t tell, it’s why there were question marks in there. Karkat’s blood is red )

( Karkat does not have all the blood, he just has candy-red. The rainbow/question marks were to show the ~mystery~ of his color. )

( Ur probably just continuing the joke, but in case you were confused by the rainbows: Karkat’s blood is bright red. The rainbow thing was just to represent how we didn’t know its color yet )

It wasn’t a joke. I really did thought Karkat had Rainbow blood. I was excited about it too damn it. A little sad that that wasn’t the case. I wanted to make more Skittle and Rainbow Road jokes.

I like how Hussie made it that Slick was the one to reveal the blood color on the knife, but the rainbow effect was way to cool to ignore. I wished they kept the rainbow thing.

So if Karkat has regular red blood, on their scale it means that he is trash of the trash. So I was RIGHT about his inferiority complex. I guess he was so low he was beneath the Troll blood spectrum.

At least he has Slick and the humans to be blood buddies with.
