Klingon blood color

[Bob the Gunslinger]

So, is their blood pink (ST6) or red (TNG/DS9)? What is the canon position/explanation?

i thought it was more purple-ish in ST6?

[Solauren]

Possible explaination:

They had been drinking earlier, maybe that was the effect of alchol on there blood.

Other explaination:
B&B continuality

Another possible explanation, though one I won't argue too hard for (as it's pure speculation on my part), would be that the Klingons have a longstanding policy of complete assimilation of subject peoples.

Klingons are known to rewrite their official history to make the powers that be look good. Klingons are also known to have had a different appearance in the era of TOS than in later eras, an appearance difference that is referred to in canon in the DS9 tribbles/time travel episode whose name I don't recall right now. Even TOS techniques of cosmetic medicine were adequate to allow a human to pass for a Romulan, or a Klingon to pass for a Romulan. Klingons also have very few visible non-Klingons operating in their territory. Klingons are famously capable doublethinkers, simultaneously despising 'dishonorable' tactics in combat but admiring their own 'guile' and cloaked ambushes of unprotected enemies. Finally, Klingons share a common genetic baseline and compatibility with other humanoid species (due to the infamous 'seed codes' from the TNG episode 'The Chase'), one that can require advanced medical tinkering but that is not insurmountable.

So...

What if the Klingons, when following their old (pre-Khitomer) SOP of executing all government officials of a conquered world and carrying on from there, then proceeded to apply other standards of their own to the subject population? The first stage would obviously be to eliminate the old records of the subject people, along with the old culture and traditions. Of course that will require eliminating a lot of the older members of the subject people... The next stage would then be the adaptation of the subject people to Klingon cultural and species standards by means of memory modification, intensive reeducation, surgical adaptation, deliberate crossbreeding and genetic modification.

With an active Imperial Overseer and enthusiastic culling of recalcitrants, recusants and excess members of the population, a conquered world with a starting population of a few billion might be converted to a fully Klingon population of tens, even hundreds of millions in less than fifty years.

Differences in the genetic cocktails of individual Klingons might account for some Klingons having lavender blood tints, others having a more conventional reddish tint.

Or not.

Or it's a trick of the light?

What was the color in Enterprise?

Red, as seen in "Broken Bow" part II when they cut Growl T. Klingon's hand.

I've heard it was made pink to avoid a higher rating by the MPAA. I think it would be much easier simply to accept an out-of-context answer and call the pink blood an outlier.

I'm pretty sure we've seen Worf with red blood too.

No, because in the end of the movie they shot a Klingon that turned out to be a Federation officer wearing a Klingon mask. They realized he was a human when they saw red blood leaking out. The Klingon stuck his fingers in the blood and held it up to the camera.

I highly doubt this would be allowed if what you say is true.

[Death from the Sea]

Klingons are supposed to have purple blood as seen in ST:VI. The red blood seen on DS9 and TNG is a special effect gaffe, lack of care for continuity.

[Thag]

Physical mutation due to fallout from Praxis in the atomosphere, maybe?

You're clearly not familiar with the MPAA; a few seconds of red blood might not be so bad, but buckets of it floating about while they go on their merry shooting spree on Qo'nos One could very well have bumped it into PG-13 territory.

I dont think that Colonel West-unmasked scene was in the theatrical release.
