No your blood is not red until it hits oxygen, that is why your veins are not red.
The above answer is incorrect. All blood is red but blood with oxygen is brighter red and blood lower in oxygen is darker red. All veins do not carry blood low in oxygen. Most do but not ones coming to the heart from the lungs.

∙ 13y agoYes, mammalian blood is red whether it is venous (in the veins) or arterial (in the arteries). Blood is never blue contrary to a popular myth. The blood in veins is a slightly darker red than that in the arteries. That is due to the extra contents of wastes that it picks up and carries from the body back to the kidneys and liver for filtering and elimination.
The myth about blue venous blood was partially started because anatomy charts usually show the arteries red and the veins blue. They are not to be considered true colors, merely a way to distinguish the vessels that are arteries from the vessels that are veins so you can learn which are which. It has just been those two colors in most charts because of tradition, not that they actually represent what the blood and vessels look like (all are red). See related question below for a more detailed explanation.

Is there blue blood inside the body and when it hits the oxygenthen it turns red?
Your blood is bright red in the artery and dark red in veins. You do not have [ blue blood ] . It only appears blue because the veins which are white are are carrying dark red blood and being viewed through the skin which difuses the light and makes them appear blue. that is partly true but I have herd from all my teachers that your blood is blue in the arteries. Which when you get cut the air puts oxygen in the blood stream that makes the blood turn red. answer #2 The statement that blood is blue inside the body and turns red when in contact with blood makes little sense. How can this be so when blood itself is used to transport oxygen throughout the body? It is not possible for blood to be blue inside the body as well as carry out one of it's main functions. Answer#3 Actually blood is red in the arteries and blue in the vein. Blood in the artery has already combined with oxygen whereas blood in the vein has yet to receive oxygen. So in fact there is both red and blue blood. When a vein is cut open it hits oxygen in the air causing it to turn red. Answer#4 The protein hemoglobin, which carries oxygen in the blood, changes shape when it binds oxygen. When it changes shape, it absorbs different wavelengths of light, making it change color. When blood is exposed to air, much more of the hemoglobin absorbs oxygen than had in the vein the blood came from (in the veins, the hemoglobin has already given up most of its oxygen to the body). Therefore, the blood turns red. This also means that blood in the body, once it has been oxygenated, is also red, though much more so when it reaches open air. I think it would be a fun experiment to put your hand in a vacuum chamber with a tight seal around your wrist and prick your finger to see the difference in blood color.
Why is earthworm blood red?
Earthworms have blood and it is enclosed in a network of tubes much like the blood system of mammals. It is red because it contains the oxygen carrying pigment hemoglobin. Unlike mammals, where the hemoglobin is inside red blood cells, earthworm hemoglobin is just mixed in the liquid of the blood, commonly called hemolymph. Earthworms pump their blood around the body with the help of 5 specialized blood vessels that contract and expand. They are the worm's hearts.
