are u just trying to confuse things even more or what??

Tell you what, Its impossible to 100% prove so meh lol.

Even if you took all of the oxygen out of the air and slip yout wrists... still wouldent be great proof...

Its like saying that the earths center is filled with moltern iron as it has the same mass... But... no one acctually knows...

Or that every bonage of chemicals have been found through lab-bonding but you can't PROVE that ether.

The world is a lie. :rolleyes:.

Just because something appears on Wikipedia, doesn't mean it's a proven fact.

Wikipedia allows users to add their own entrys and opinions, so just because you got it from there in no way means it's correct.

I still stick by my original hypothosis, that de-oxygenated blood is blue, and oxygenated blood is red.

I never said it was definite, you can't actually trust anything you see on any site, though Wikipedia is often correct and provides accurate information.
There are many things that back this up:

"The color of blood never actually is blue. When it is in the oxygen poor stage is does assume a red color that is not as intense as the red of the oxygen rich stage. When viewed through the skin this darker shade of red does appear to have a blueish color." SOURCE

"Blood gets its bright red color when haemoglobin in red blood cells picks up oxygen in the lungs." - i.e when it is still in the body. SOURCE

There are more.. I can provide you with more if you wish. But it seems that Blood is always red, though just darker (almost purple) while within the veins.

Precisely, I suggest everyone goes to their nearest hosptial and have a blood test. It is a dark red. You cannot say it has been oxygenated in the test because there is no oxygen inside a needle... Because if there was, it won't be good if it enters the body...

The red blood cells are only in your blood coming out of the heart... in arteries... when the blood is being pumped back into the heart they are goin thru veins, after theyve dropped off the oxygen to different parts of your body. so veins are blue and the blood inside is blue but in arteries they are red and always are...

Theres your answer people.

Theres your answer people.

That is very false.

[Nixt]

Theres your answer people.

Nope. It is just a deeper red, almost purple colour, when it is passing through veins.

There is oxygen in the needle. It has been in contact with oxygen and therefore when it contacts the blood, the blood inside the needle turns red.

Nixt, you say blood is a 'dark red/purple' colour - therefore, in some peoples eyes the blood is purple, whereas others would call this purple - blue.
