iron.
hemoglobin has heme groups (complex molecules made up of carbon, hydrogen, oxygen, nitrogen and iron) and proteins (the globular or "globin" part). all of these except iron appear elsewhere to form all kinds of different colors: skin, eyes, organs, etc. but when you throw iron in the mix, everything goes red.
different minerals in organic compounds will give you different colors. when you mix iron with oxygen in nature, you get red most of the time. for example, rust is basically iron and oxygen.
oh and one last thing to the other people who answered this question: OUR BLOOD IS NEVER BLUE. this is akin to saying the earth is flat. it's an old wive's tale that never got straightened out in some people. the reason our VEINS appear blue is because they are whitish, they are filled with darkish liquid, and they are close to your skin which depending on your skin color, ranges from dark brownish to yellowish. when it is oxygenated, blood appears very bright red, when it is deoxygenated, it is a deeper, darker red. blue never comes into the picture.
to test this, go into space and cut yourself.

The hemoglobin makes the blood cells red.
he scientific name for red blood cells is erythrocytes. They are formed in the bone marrow and are created by a stem cell. Red cells are the most numerous of all blood cells in the blood. They are produced at a rate of 4-5 billion every hour in an adult human!
When a red cell matures, it ejects its nucleus before entering the bloodstream.
It looks like a doughnut, but without a hole in the middle. Red cells are 7-8 microns in diameter. Yet, they are the heaviest particles in the blood.
Red blood cells contain hemoglobin, a protein that carries oxygen. Oxygen is known as O2. Each time we take a breath in, we are inhaling oxygen in the air.
The role of red cells is to absorb oxygen through the little alveoli in your lungs and deliver it to all the muscles, tissues and organs in your body.
To do this, they travel through large arteries and tiny capillaries. Sometimes the capillaries are so small, the red cells have to squeeze and bend themselves in half to get through in order to release their load of oxygen!
But that's only half the trip! After they deliver the oxygen, the red blood cells pick up a waste product called carbon dioxide, known as CO2. Then they make the return trip back to the lungs through the veins where the CO2 can finally be released. The body eliminates carbon dioxide every time we breathe out! Then, the red blood cells start the trip all over again.

The red blood cells, called erythrocytes, contain iron. This is important to carry oxygen to the cells in your body. And this sort of iron is called hemoglobin. If your level is low you might get tired and indeed rather pale - looking just sick.
Actually the blood itself, the serum, isn't red but yellowish. Just the erys (so we cut the word short) make it red.
Hope I was able to help. Don't know if I wrote the words right because I'm German...

Technically it is oxygenated hemoglobin that makes your blood red and that's why arterial blood is not the same shade as blood from a vein.

Hmm...... Everybody's blood is Red. Hemoglobin which is present in red blood cells gives that colour.

its not its blue. but when your bleeding there is a reaction with oxygen that turns ir red. a little strange considering we use oxygen to pump blood around our bodys. dont ask me...i didnt conclude this theory.
i wonder why blood feels oily. i think some creatures can produce oil maybe the americans have been killing so many people for the oil quite literally

Blood consists of 3 types of cells- RBCs,WBCc & platelets. Of these RBCs r red in colour due to the presence of a compound called HAEMOGLOBIN. Haem means iron (Fe) & globin means protein.Now Fe is red in colour(as u now). This is what gives blood its red colour.Psst-But for RBCs our blood wouldn't b red!
P.S.- Haemoglobin is the oxygen carrier.

Your blood is red because heloglobin is in the cells which gives it that colour. red comes out of your veins and its black blood when it comes out of your arteries, but hopefully you'll never see that!

Your blood is actually blue. When it is exposed to the air(oxygen) a chemical process takes place that causes it to turn red.

Hemoglobin, which carries oxygen, makes it red. The more iron-rich and highly oxygenated your blood is, the more red it is.
