We know Marceline can not only drink blood, but colour too. But

haha dude its just a cartoon turn off your brain and watch lol

Colors are variations in the wavelength of light. She can alter the atoms of a substance to reflect a different wavelength than they previously did. The alteration of the atoms itself is a way to siphon off electromagnetic energy.

realy makes you think

*it's just a cartoon

Which brings up an important question:
Does Marceline become Superman if the planet's orbiting a red sun?

>>94509478
Fuck you Craig you crackhead looking motherfucker

>>94512887
No, but she probably doesn't feel as hungry.

>>94509454
>And if so, does this mean that if Marceline went blind, she wouldn't be able to drink colour anymore, just blood?
She must have Moon's healing powers to some extent, maybe those are designed for such cases specifically

This actually seems to make sense

>>94509454
Colors do exist beyond on our perception. It's just that we've discovered them and applied a name for them. The color red is the color with the longest wavelength that's visible to humans. There is an actual range in nano meters for what perceive as red. She can feed herself regardless if she could see the color red. That wouldn't make sense otherwise assuming that it's more likely object reflecting most light within the red range. This is of course assuming that eating a color makes any medical sense to begin with. It's difficult to apply real world explanations for situations in a universe where a heterotroph can sustains themselves with light. That's biologically impossible.

It might've made sense if she had a drastically different anatomy from humans, including eye organization. She does turn into a bat, but IIRC vampire bats can see colors too?
