In summary: "you're as blue as a ball of ice.") deoxygenated blood doesn't contact oxygen, so it turns dark red.

What if you have no evidence to support your theories? What if you just keep posting for the sake of posting?


Answer: You go to the principals office.

Please provide a refereed reference that shows the measurement of the colour of non-clotted deoxygenated blood, stating the level of deoxygenation of the blood.

Who ARE you and where are YOUR references. All I see you doing is making claims that because Iron sulfate is greenish blue that it means that porphyrin in our blood doesn't make our blood red. YOU need to substantiate what your saying about de-oxygenated blood having an effect. This will go on forever if you just keep making up scenarios and requesting evidence oh-contrare.

Sorry, other than the OP's brother, is there any serious dissent that oxygenated blood is bright red and deoxygenated blood is darker red?

If not, are we arguing for the sake of anything more than because we like the sound of our own voices?

See the two references in post #38, and http://omlc.ogi.edu/spectra/hemoglobin/ .

I would guess:
Is hemoglobin blue? No, it has a huge absorption peak in the blue.
Is deoxyhemoglobin bluer than oxyhemoglobin? Yes, it has a larger absorption peak in the red.

This is all pointless. The question is asked and answered. Thread locked.
