“In humans and other hemoglobin-using creatures, oxygenated blood is a bright red in color. De oxygenated 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 before venous blood is exposed to air it is blue.”

That is not true at all. All blood is a rust color, and when it comes in contact with oxygen, like when your doctor draws your blood, it turns really red. Veins only look blue because of your skin.

Blood is red.
Dark red if it's deoxygenated, bright red if it's oxygenated.
It's red because of the red haem groups in red blood cells - which make up most of the non-water blood.

I believe that the veins and capillaries are just blue not the actual blood.
