No, only in diagrams. Even deoxygenated blood isn't blue.

No.
If you want to say Human Blood then,RED.
The cellular constituents of blood are: red blood cells, which carry respiratory gases and give it its RED color because they contain hemoglobin (an iron containing protein that binds oxygen in the lungs and transports it to tissues in the body)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 color. 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.

When blood leaves the lungs, it is rich in oxygen and carries a blue tint. As the blood circulate the body and feeds the cells of the body, oxygen depletes and carries a more red tint. When you look at blood thru the skin, the skin pigmentaion cause the blood to look blue. All in all, it is red.

no. it is always red

no

De-oxygenated blood is blue. This doesn't happen often, though. Blood recieves oxygen when you breath in and never really uses all of it up when it disperses throughout your body, so it reamins red all of the time.

Blood can be blue or red because when blood does not have oxygen in it,it is blue and when it has oxygen,it is red.
