The blood inside our human body is red. More specifically, depending on the oxygen saturation level, the shades of red varies. Blood which contain high amounts of oxygen, mainly found in our arteries, is bright red, while blood that has had the oxygen consumed, i.e., deoxygenated blood found in our veins, will appear as dark red.

The reason why our veins appear blue is not due to the color of the blood being blue, but rather it is an effect of light scattering and absorption upon diffuse reflectance.

The color red of the blood is created by the oxygen carrying molecule known as hemoglobin. This is the molecule that captures oxygen molecules and release it at various places in our bodies due to diffusion.

Blood inside the human is always red. Many people (including me ;D) think that some of the blood is blue. Usually, this is because our veins appear blue and diagrams usually show deoxygenated blood blue.

Blood is not blue. The colour of blood ranges from bright red (oxygenated) to dark red (deoxygenated). We only see blue blood in veins because of a trick of the light. Further more, blood is made up of plasma, red and white blood cells and platelets. The red blood cells contain haemoglobin which gives the blood its red colour.

Human blood is always red, just different shades. It's a bright red in when oxygenated and a darker red when in the vein, when the red blood cells are loaded with Carbon Dioxide.

In response to the previous user, if it was Carbon Monoxide we would eventually die as our red blood cells are unable to separate from the molecule.

Oxygenated blood is carried by the arteries. It is bright red. Deoxygenated blood is carried by the veins. It is more of a dark reddish-blue.

The human blood is red when their is oxygen in the red blood cells and blue when the red blood cells are fill with carbon monoxide.

Blood is always red and is actually never blue inside the human body.
