Your blood is now a different colour...

[Quellist]

My blood is now perfect reflective silver and my power is to become a perfect copy of anyone I can see, when i become them i have access to all their skills and memories while still personally being in control

 

[Roofstone]

My blood is now a white colour with a light pink fade in it. And I can turn invisible!

Dressing rooms ahoy!

 

[Hana_aoki]

My blood looks like music. My power is synesthesia.

 

[night_tiger9]

orange. pyrotechnia!! or maybe regeneration... yea regeneration

 

[Captain Pirate]

Purple, and temporary super-strength.
Purple blood would be so badass.
I mean, so would super-strength, but come on, fucking purple!

 

[CrazyGirl17]

Huh, looks like my blood is black now. That might explain why I can now form my own weapons...

 

[Firehound]

My blood is black. It gives me the power to die horribly over a prolonged period of time. I try not to use this super-power.

 

[grizzlyAssuager]

My blood is now correction fluid white. My superpower is an increased skill in typography, and the secret ability to wipe all Comic Sans off the face of the earth.

 

[neoontime]

My blood is black.
Now I can repeatedly annoy people with that line.
I guess I can explode things with it?

 

[Joby Baumann]

I'm gonna go with clear, it grants me a hightened sight, I can track bullets, and perceive time in a slow-motion similar to May Payne, as a bonus, if I concentrate very hard I can see through things that light is capable of passing through, like for example, women's clothing...

 

[BaronOfStuff]

Blue. And I can turn invisible for 15 - 20 seconds.

 

[ThunderCavalier]

Blue, and telekinesis.

Squeeeeeeeee. Now I can do my homework without the need for a pesky thing such as a desk.

 

[Russian_Assassin]

Soul Eater fan?

Well, while I did enjoy the anime, I was thinking about Dead Man Wonderland (The Branches of Sin, to be precise), with a small hint of Crona's powers added (I also love black, so the color was coincidental).

 

[Philip Petrunak]

It's still red, but when it pools on the ground parts of it change colour to make the image of Ricky Gervais giving you a sideways smile.

 

[deathninja]

Yellow-Green, and I would spit acid.

(oddly enough, my system is weirdly acidic IRL...)

 

[Carnage95]

A glowing whitish-blue, I am able to regenerate any part of my body and gain superhuman reflexes!

 

[kazeryu]

My blood is fluorescent yellow and I light up in the dark.

 

[Emilox The Great]

My blood is lime green, and it grants me total control over anyone who drinks it.
Yay! World Domination!

 

[thatcanadianguy]

OH MY GOOOD! my blood is rainbow FAAABULOUUUUUS!! my powers include a FAAAAAR better understanding of subtle colour shades, such as hint fiji, and fuschia breeze. AND the ability to make hetrosexual men more uncomfortable than a starched wool thong!!

 

[TheLoneBeet]

My blood is black. I can morph my body at will into any shape or form. If I take longer than 30 seconds to make up my mind of what I'm becoming, then I'm stuck for 40 seconds in whatever awkward and incredibly painful form I was left in.
