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.
