When you get a cut your blood usely looks red. but in the inside it could be any color. it could be blue, yellow pink, purple, orange! but there is really no way of figuring out cuz if yo cut someone up there blood would touch the atmosphere it changes to red. i hope this answer help u!
EDIT-
Actually deoxygenated blood is dark red in colour, many maintain that it is blue but this is just a common misconception NOT supported by fact, It is biochemically impossible for haemoglobin to turn blue.
Oxygen poor blood is red. It's just a darker red than oxygen rich blood. There's a common misconception that blood in the human body is blue. However, this is far from the case. It's just a much darker red.
De-oxygenated blood is called "hypoxemic". This may be either because the body is not taking in enough oxygen for some reason, or that the blood is "venous" blood which is returning to the heart. Once passing through the heart, it moves to the lungs where the carbon dioxide passes from the blood into the air sacs of the lungs and then is exhaled from the body, and the blood "picks up" oxygen, sending it out to the body via arteries.
Your blood is actually always red! Blood in your veins has very little oxygen and is a dark red color that looks almost blue when covered by your skin. Your arteries have bright red blood because it has a lot of oxygen in it that is being carried throughout your body to be used by tissues.
it's blue when it flows in your blood stream with little oxygen it turns red when the blood has contact with more oxygen
It is Dark-red.
The color is a darker red.

Oxygen-poor blood is dark red; oxygen-rich blood is bright red.

Capillaries change color as they pass by body cells as the blood they contain loses oxygen. Oxygen-rich blood has a brighter color than oxygen-poor blood.
When blood is oxygen-rich, it is bright red. Therefore, when blood is oxygen-poor, it is darker in color. When oxygen-poor blood flows through the lungs from the pulmonary arteries, it gets rid of the carbon dioxide and picks up oxygen, which then becomes oxygen-rich blood with a bright red color.
Venous blood is oxygen poor (in comparison with arterial blood).
Oxygen poor blood
Lungs are pink in color because they are full of oxygen rich blood. Oxygen poor blood, on the other hand, has blue color to it.
poor
no you have oxygen high blood.
The pulmonary artery carries oxygen poor blood and the pulmonary vein carries oxygen rich blood.
If the oxygen-rich blood and the oxygen poor blood mix the amount of oxygen becomes diluted. The cells and tissues need more oxygen than they will get.
Any bleeding when the blood is exposed to oxygen turns the color of the blood to bright red and is called oxygen-rich. If the blood has used up a portion of the oxygen it is carrying, called oxygen-poor blood, it turns to a darker brick-red.
