Both, it depends on if it is oxyginated or not

both

same as yours....check it out for yourself

In most parts of your circulatory system - In an artery it is red. In a vein it is blue. But in the pulmonary artery, which come from your right ventricle it is blue because it is going to your lungs to get oxygenated. In the pulmonary vein, which goes to your left atrium it is red as it is freshly oxygenated and will be sent to then out your left ventricle to the rest of your body to perfuse your tissues with oxygen, glucose and much else besides.

it is blue in the body..when it gets oxygen, it turns red..that is why blood is red when you see it outside, like in a cut or something....

Blue til you get cut then when it meets oxygen it becomes red.

Oxygenated blood carried by arteries is red, non oxygenated blood carried by the viens is a dark purplish red color. None of my blood is blue.

We all bleed red , no matter how Blue the blood in our veins

I think once blood mixes with oxygen it turns red.

No. Veins look bluish through the skin, but the blood is not blue. I have donated blood many times. The blood is taken from a vein and does not touch the air and is not blue. It is not bright red like oxygenated blood, but dark red. (Oh... unless you are not talking about mammal blood... some insects might have bluish blood... but they don't have veins... I don't know about all the animals, I assume you meant humans.)

Blood is never blue. Veins appear blue due to refraction of light.

What color is blood …really ? Human blood is made up of a liquid part and a solid part. The liquid part, when it is still in the body, is called plasma. It is yellowish in color. It makes up about 50 - 60 % of our blood. The solid part is made up of cells; red blood cells, white blood cells and platelets. White blood cells and platelets have no color but appear white when they are grouped together, as when blood is separated in a centrifuge. Together they make up less than 1 % of the blood. They are pictured in text books as having a variety of colors. This is because they can be stained with various dyes after they are removed from the body then placed on a glass slide. Red blood cells are always red. Since RBCs make up about 40-45% of our blood, the blood is red. Red blood cells are red because they have a protein called hemoglobin which contains iron. Iron likes to bind oxygen. Oxygen combined with iron is red. The more oxygen iron has bound to it, the redder it is. It is true that some persons have "iron poor blood". In this case their red blood cells are less red than normal, but they are still red. The iron in the hemoglobin of red blood cells is what carries oxygen to every tissue in the body. Why some people may think that blood can be blue is probably because of the color of our veins, which may be visible near the skin's surface. They appear blue because they do not get as much oxygen as the other tissues. When the red blood cells go to the lungs, the iron in them picks up oxygen. Blood then goes to the heart and then to the rest of the body through vessels called arteries. The arteries appear reddish as do many other organs, because the iron in the blood gives up its oxygen to the cells that need it as the red blood cells travel throughout the body. By the time the blood is back on its way to the heart and then to the lungs it has less than half as much oxygen as it did before. The veins, therefore, do not get as much oxygen as the other tissues and they appear bluish. The bottom line is: blood is red.

Blood is *never* blue. Blood is described as dark red (venous) or bright red (arterial). Our veins look blue because we are looking at them *through* our skin. It's a color of the distended vessel wall itself, and has something to do with collagen or some other protein. The blood inside them is dark red and it doesn't reflect light very well. The blood you see when you get hurt is usually venous blood. Arterial blood comes out in spurts. It spurts every time the heart beats. I hope you never see that.

Red, red, red. Always. Well, unless you're a molluscs. :D or colorblind?
