No...courtesy of wikipedia who phrased it far better than I could
"In humans and other hemoglobin-using creatures, oxygenated blood is bright red. This is due to oxygenated iron in the red blood cells. Deoxygenated blood is a darker shade of red, which can be seen during blood donation and when venous blood samples are taken. However, due to an optical effect caused by the way in which light penetrates through the skin, veins typically appear blue in colour. This has led to a common misconception that venous blood is blue before it is exposed to air. Another reason for this misconception is that medical charts always show venous blood as blue in order to distinguish it from arterial blood which is depicted as red on the same chart."

Blood is a bluish purple color in the artery's as it returns from the extremity's of the body to the heart. The lungs enrich the blood with oxygen, then it's pumped back through the vains supplying the body cells with oxygen. From the time the blood leaves the lungs it is red.

Yes, you are correct. When blood hits oxygen, the hemoglobin within it changes colors. The blood within your body also can turn red whn it collects oxygen to be sent to other parts of your body, and when the blood gives the oxygen to the body part it turns blue, and goes back to the heart to get more oxygen. It's a continuous process. If you want to learn more, google it. Even better, never doubt the almighty power of wikipedia.

No, your blood is always red. It appears blue on its way back to the heart. The "blue" color is actually dirty blood (blood that has absorbed carbon dioxide), then it's pumped through the heart and "revived" with oxygen.

yes, but I think it's different shades... for example, the blood coming from the lungs to the heart is much more red... because it was just getting oxygen (from the lungs)... I would think the most bluish blood would be that coming from veins since it has the most deoxygentated blood...

depends if the blood is oxygentated, the oxygen turns the iron in your blood red, deoxygenated blood is naturaly blueish

arterial blood is red(it have oxygen in it) venous blood is kinda of violet (after oxgen leave blood)
