it is blue and when it hits the air it turns red.
and when it is drawn from a needle, it comes out of ur body,a so it has to hit the air.

It is blue in the body, red outside. Remember, a needle also has a small bit of oxygen in it as well. As soon as blood exits the body it is red.

Blood is red!! I have had this argument with HUNDREDS of people and have to prove this so many times it is pitiful! Blood without oxygen is dark red with a blueish hue.

All the people saying it's blue has no idea what they're talking about. It only appears blue through the skin, venous blood (unoxygenated) is a dark red, while arterial blood, oxygenated, is a bright red.
So stop spitting what you heard from your friends moms brothers cousin

When blood has no oxygen in it, it is blue (that's why when you hold your breath too long your face turns bluish, your blood runs out of oxygen). However, when it does have oxygen (from red blood cells) it's red.

Blood is never, ever blue. Blood is always red. The reasons our veins look blue is because you are looking at them through skin and the blood that is inside the veins does not reflect light well.
It has nothing to do with air hitting anything. That does not magically change the color of blood.

blue blood is when the blood has been through the heart and stripped of oxygen. red blood still has oxygen in it, which is why it is red whenever we see it outside our bodies

Blood is never blue. It is either dark red or bright red. It looks blue because we are looking at it through our skin. The blood is dark red and does not reflect light well, so we don't see the true color through skin.

They always talk about blue blood when it comes royalty.
All blood is red. Oxygen rich blood is bright red while the blood deprived of oxygen is a dark red color.

The changes that occur in blood upon oxygenation and deoxygenation are visible not only at the microscopic level, as detailed above, but also at the macroscopic level. Clinicians have long noted that blood in the systemic arteries (traveling from the heart to the oxygen-using cells of the body) is red-colored, while blood in the systemic veins (traveling from the oxygen-using cells back to the heart) is blue-colored .The blood in the systemic arteries is oxygen-rich; this blood has just traveled from the lungs (where it picked up oxygen inhaled from the air) to the heart, and then is pumped throughout the body to deliver its oxygen to the body's cells. The blood in the systemic veins, on the other hand, is oxygen-poor; it has unloaded its oxygen to the body's cells (exchanging the O2 for CO2, as described below), and must now return to the lungs to replenish the supply of oxygen. Hence, a simple macroscopic observation, i.e., noting the color of the blood, can tell us whether the blood is oxygenated or deoxygenated.
