No its not.
On diagrams of the cardiovascular system they show it up as blue so u can distinguish de-oxidized blood from oxygenated blood.
The "blue blood" is in your veins. It is rather a more dark/deep red.

Ha ha. No - blood is never blue, but it does come back from the body a purple color. After the heart has pumped your spent blood through your lungs, it comes back bright red to be recirculated. The color is oxyhemoglobin and that is what gives a healthy pink glow to your body. The only people I have seen with genuinely blue blood were dead.

purple but when it comes out its red I'm guessing because it's a very dark red when it's inside your body

Blood is red. When they draw blood it goes into a tube. Doesn't touch air. It's red.

The blood from your heart in your arteries is red because it is oxygenated to be circulated through your body and deliver oxygen to the tissues via the cardiovascular system. After the oxygen has been extracted from the blood and used by the tissues, the deoxygenated blood in your veins is "blue" as it returns to the heart for reoxygenization (through your pulmonary circuit when you breathe), and ultimately recirculation, where it becomes red again.

Red blood cells carry oxygen through your body, so they always contain oxygen. Thus, your blood is red.

It has to be a mixture between really dark purple and blue. The reason it looks red when you cut yourself with a paper cut (etc.) is because the air rushes to it. The air makes it rich and red.

No! Blood is never blue. Even if some people say that deoxygenated blood is blue, it is of deep red colour as compared to light red colour of oxygenated blood.

Due to haemoglobin which is red pigment and is present in blood , it's colour becomes red thus it gives red colour to blood and help in transportation of oxygen.

yes and it turns red when it meets oxygen because the iron in your blood goes through a chemical reaction causing both the red coloration and the iron smell

Due to prescence of haemoglobin which is red pigment and is present in blood.

blood in veins without oxygen is a dark purple it then travels to the heart gets pumped through the lungs gets oxygen turns bright red back into the heart and shot out through the arteries as red blood until it drops off the oxygen to the cell tissue then its purple again
