View Full Version : The color of Tau blood?

Hey guys, I'm drawing a pic of a Tau who has been the victim of a Howling Banshee's sword. There's a spray of blood from the swipe. Here's a question, what color is Tau blood? If it was up to me, I'd probably make it like dark blue or inky blue. But .... I'd like to stay close to fluff if I can.

Anyone remember what color their blood was described as in any of the fluff?

Thanks for the help!

Something between cyan and cobalt blue, I believe. Beyond that, I can't give many answers - whether it is cyan or blue probably depends on how oxygenated it is.

Red.

For the same reason that Ork blood is red (instead of green as some think it should be). Because it stands out against the skin and makes for a sense of the dramatic. If Tau blood were blue it would blend in and not *pop* so much.

On a *reality* (sorry:() level, if you think skin colour should dictate blood colour, take a gander at humans and other mammals....all have red blood because of the haemoglobin.

Unless of course GW wants to rewrite biology with their *vast*:rolleyes: knowledge of the subject...;)

Well to be fair ork blood USED to be green, but was retconned red.

All the algae and fungus within it made it green. I used to paint ork blood bright green, on the order of scorpion mixed with bad moon - like Predator blood without the luminescence.

I believe Fire Warrior referred to it as blue, and didn't Xenology make some comment about it?

Well, just to clear things up, I don't think skin color dictates what color blood is. But however, I did say blue or inky blue because....I think it would look cool. No scientific reason what so ever behind that statement. :)

Hmmm...really? Seems like the general consensus is blue. But does anyone know for sure ....for sure? If not, I'm gonna go with blue. Heh heh.

Ha ha ha! Aw man...don't be like that......

Don't worry, I'll do some pics of Tau kicking butt too. Its just that I wanted a pic with no Imperials in it. Also, this is how our friends and I talk smack to each other. I draw a pic of an Eldar killing a Tau. Then my Tau friend draws one of Tau shooting down our Grav tanks, then my Tyranid friend draws one of a Hive Tyrant slicing both Eldar and Tau! That's just how we are. ;) Plus, I want to fill my gallery up with more 40k pics.


I'll eventually draw something from every army/race.

BTW, if your friend tolerates bad and ugly writing (and is older than 18), he might get a kick out of reading Goto's Eldar novels (esp. Dawn of War: Tempest) where Eldar are slaughtered and mutilated on every page. If you like Eldar, keep away from those books.

I've always been under the impression that Tau blood is Hemocyanin like horse shoe crabs.

Also I always thought Ork blood was black but oh well.

Thanks for the links to previous threads! Some reason, when I do a search, my computer goes to a broken link or I just get no results. Both my Tau friend and I read BL novels, but ....just seem to be unable to finish any Eldar novel by Goto.

More like crimson actually, but I've also had it described as green or even purple (which would look nice by the way). Unfortunatly I don't own a copy of Xeneology which I believe is the most recent source on these things.

And Warp, could post the pictures in the Art and Stories section when you're done? We all have an appreciation for fine art. :p

In the Ciaphas Cain trilogy, he fights with Tau as an ally against the Bugs and when one gets shot he bleeds blueish purple... And Cain remarkes that that's most likly why there skin is so blue....

I've always thought of it as blue. However, it's open to interpretation what shade of blue it is and whether it is blue or purple.

However, I'd make a bluey-lilac, just because it would look snazzy.

No, of course not, but why can't the Tau have blue skin without it having anything to do with the color of their blood? And far as I know, the Tau have not evolved on Earth and as such wouldn't have to have hemoglobin for blood.


Unless of course GW wants to rewrite biology with their *vast*:rolleyes: knowledge of the subject...;)
Well, that shows what you know. Hemocyanin is the second best blood know to man next to hemoglobin. It can't transport oxygen as well, but better than the rest. The color of hemocyanin ranges from purple the teal, depending on the oxydation, like how hemoglobin ranges from different shades or red.

The stuff can be found on horseshoe crabs for one.

Well, in the Ciaphas Cain novel, it is said that Tau blood is really dark, almost blue, in color, something to do with the amount of cobalt in it's bloodstream, or something to that effect. So yes, they bleed blue.

As has been stated before, the Tau blood is blue as they have cobalt in their blood rather than iron.

Of course, humans have blue blood as well, well blue-ish, but when exposed to oxygen it's red.

Skin colour doesn't effect blood colour, but blood colour does have an effect on the skin colour. Human skin is a yellowish (Caucasuian is anyway) translucent colour. Combined with oxygenated blood, it gives us the 'pinkskin' look, in effect, muting the red (like using a gel filter on a strong light source).

Tau blood is a bluish colour and the skin is said to be a greyish colour (one of the blue-greys, as opposed to the black/white greys) as a result.

If you value your sanity, don't read any CS Goto.

Read Mills and boon instead. Writing's just as crap, but at least they aren't butchering your favourite game background.

Actually it goes for non Caucasians as well. From brown, black, tan, or white all of the colors of human skin have at least a little red tinge to them. The very nature of variation in human skin color being based on brown and black of melanin.

[please, no expressions of sympathy are needed. It was a few years ago now.]

Cuttlefish have a copper based blood, iirc, and wierd eyes, though so they must be xenos.

Horseshoe crabs (and most molluscs) use haemocyanin (which is a dumb word conjunction but anyway) rather than haemoglobin.

It's only blue when it's oxygenated, and only a real deep blue when it comes in contact with the air - oxygenated haemocyanin within an organism is generally greyish yellow.

I assume this is what tau blood is based on (considering Xenology also made their heart analogous to a kidney or liver as well).

Tau is blue.

Human is never blue. when it does not carry oxygen it becomes a deeper red. Hemoglobin is a red pigment.

It's an old codex. It also suggests that Farsight is old as hell and stuff like that, all which have been dropped in the later codex. All sources after that mark Tau blood as blue, so I'm willing to go with that.

So I prefer the old ways, whatever. Farsight's still ancient, the new Codex doesn't retcon his background of fighting orks and participating in the 2nd Sphere expansion, it just doesn't explicitly mention his extended age anymore. And with what we know about the advanced state of Tau technology I see no reason to believe they don't have the ability to extend the life span of their important personalities - something's keeping Aun'va alive and I prefer it to be Tau super-tech rather than some other race's meddling.

I'm sure if I was around during 2nd Ed I'd prefer the old backgrounds for everybody else too.

This is true. If you read the Inquisitor Vail citation at the bottom of the page she says it's because Tau blood has cobolt in it, rather than Human's (superior) blood that has iron.

For what it's worth as a reference, The game "fire warrior" had tau with red blood.

I'm noticing that written sources tend to have it as blue while visual have it as red.

Red blood is just easier to make look good on models I'd say, that was the reason they gave when they said Orks blood was read, I think.

Tau blood is somewhere between purple and reddish purple (depending on oxygination). This is because theyre hemoglobin contains cobalt instead or iron.

I don't remember much seeing blood in the game. There were some disected Tau corpses, but just because the internal organs might have red in them, doesn't have much to do with the color of the blood. Myoglobin is what gives muscle tissue its red color.

But artists tend to make things look good rather than keep with the stuff written down.

Why does this remind me of Red vs. Blue?
"It's not pink, it's lightish red."

Hemoglobin = Iron based.
Hemocyanin = Copper based.

I pretty much just stole that quote from Amberley Vail in the 1st Ciaphas Cain novel.
And bloodcolour does depend on the amount of oxygen its carrying. Bleeding from an arterie will result in lighter coloured blood then bleeding from a vein.


Hemoglobin = Iron based.
Hemocyanin = Copper based.

So sue me for not knowing the correct term for hemocobaldin :P

Well, the fluff suggests blue/teal/purple, which helps with the "alien" aspect of the tau. Hemocyanins are very efficient for environments in high O2, which i expect their homeworld to be.

something else to point out: Just because they use hemocyanins does not mean they are easy to tire. their bodies almost certainly have adapted to utilize it far in excess of anything we have ever seen.

Why did Cain think it had to do with skin? because he is an uneducated human who knows nothing about xenobiology. He probably doesn't know why our skin is varying shades of brown, or why we have five fingers to each hand.

Oh, and GW is trying to retconn it to red, because, well, they are more concerned with pretty models then a decent fluff.

Where is it said it's cobalt? I'm not contradicting it, I'm just interested. Hemocyan has copper not cobalt. Oxydated copper is teal/blue the same way oxydated iron is red.

Of course it's not like their authors read the old background material before they start writing new stuff: so Author A writes it blue in his book, Author B writes it purple in his, Author C writes it red, etc.

I suppose the "best" answer would be to use the most recent publication (following their stance on the rules). So not red, but which of those other books is newest?

So tau are the blue bloods then <snicker>.

sorry to add that, it was terrible. But I believe tau have blue blood because not everthing out there in the big ol galaxy is going to be exactly like earth. That means that other alien species may have a different biochemical make-up.

The other reason is cause blue would look awesome as blood on some of the sept colours? what sept were you doing OP?

It's amazing how people (and by 'people', I mean fanboyz) can't decide what they want. Many scream that aliens need to be more alien, but when you get weird stuff like non-red blood and crystalline poop, it's just wrong. What do you want?!

To tell the truth, I don't see anything wrong with things like Eldar poop. Maybe the wording gave people the impression they excrete solid crystal rods. For one, the smell of ordinary stool is the result of bacteria. I wouldn't put past the Eldar to have a more advanced system that works without a 3rd party in the process (they were made, not evolved after all).

As to the actual form of it, many creatures even in our world have different ways of expending their excrement. Some dispose it in neat packages for example. Crystals aren't just those pretty colored things. It doesn't mean it's solid sharp pieces of glass. Even pearls are made of crystalline calcium carbonate. For a such advanced race, one would assume their digestive system to be able to process nutrients far more effectively than what we have.

sorry if someone already mentioned this but-


In the Cain novels, (first one i think) the ordo xenos inquisitor explains.

Tau blood is blue, this is NOT because of skin color. Tau blood contains alot of cobalt, while human blood contains alot of iron

Iron=red
Cobalt=blue

When the biochemistery is examined cobalt content in blood probably dosent make sense. (i wouldnt know but it sounds wrong)

But neither do aliens and demons so who cares.
