Mostly a very dark brownish red, although when you look at them through many people's skin, they look blue. This is an illusion, caused by the reflective factors of the skin, that gives the appearance of blue. This pertains to the veins themselves and the venous blood; both look blue through the skin. Deep bruises look bluish red for this reason, we can see more of the red color since the blood of the bruise is closer to the surface than veins, that look very blue through the skin. The arteries are much deeper in the tissues where they are less visible and have less of the reflective factor involved, but they are also red. The blood in arteries is a brighter red than the brownish maroon color of venous blood. During vascular and endovascular surgery and direct visualization, the true red colors are visible.

Why is the color of blood is always red in color?
Blood is always red (NEVER blue) because of hemoglobin, the main factor in blood's color. Deoxygenated hemoglobin is dark red, while oxygen enriched hemoglobin is more cherry red. The common misconception that deoxygenated blood in your veins is blue stems from textbooks that show arteries in red and veins in blue for simplicity. Also, your veins appear blue through your skin because of a variety of reasons only weakly dependent on the color of the blood. Light scattering in the skin, and the visual processing of color play roles as well. If arteries were near the skin surface, they would appear blue as well. Cameras inserted in veins during medical procedures clearly show that blood in veins is red, and when drawing blood from veins in a way that doesn't expose it to the air, it is clearly a dark red color and not blue.
