Vein color is usually dark red- not blue as commonly believed- this is a result of low oxygen content in this blood. The vein appears blue because the subcutaneous fat absorbs low-frequency light, lettling only blue wavelengths penetrate through the dark vein and reflect off. The real only difference between dark blood and brighter red blood is the oxygen content in the blood.
The whole point of dark matter is that it doesn't interact via the electromagnetic force (that's what makes it "dark"). It's therefore largely unaffected by normal matter (except through gravity), and could go straight through your body... or a lead wall, or the Earth... without you even noticing. In fact, if dark matter really exists, that pretty much has to be happening all the time.
The color of skin that is supplied by oxygen-poor blood is bluish or purplish, commonly referred to as cyanosis. This occurs when there is a lack of oxygen in the blood, leading to a darker coloration of the skin.
Very dark red.
As it gives out oxegen it looses the bright red
It meets oxygen

The oxygen in it is replaced with carbon dioxide.
Because of the high amount of blood that circulates through the liver.
After blood is oxygenated, it turns from a dark maroon to a bright crimson color. The cell circulates around the body distributing oxygen to other cells before becoming depleted of oxygen and returning to the lungs to get more.
Their white and red blood cell drops causing anemia. No blood circulates around cells around the eyes?

If you bleed dark brown blood when you cut your finger it means you are alive........ at least your body is.

Oxygenated blood is bright red and deoxygenated blood is darker red.
