The haemoglobin molecule.
This a very large molecule, consisting of a porphyrin ring and at the centre of this ring is an iron ion in oxidation state '3' (Fe^3+)
Iron ion in this oxidation state is red/brown in colour. Compare with iron ion in oxidation state '2' which is green in colour, and rather unstable to the point that it will oxidise to oxid'n state '3' quite readily.

∙ 8y agoShort answer: Blood is red because of hemoglobin, an iron containing material that is able to both absorb and release oxygen and is one of the most essential parts of blood. When it has absorbed oxygen it is bright red in color and when it releases oxygen it is dull red.
Long answer:Our blood contains many different materials and cells, each with a different purpose. Plasma, the liquid portion of the blood, comprises more than half of the blood. Plasma is light yellow in color, and is thicker than water, because it contains many substances, in addition to the actual blood cells. These substances include proteins, antibodies, fibrinogen, which helps blood clot, carbohydrates, fats, salts, etc., and when it is returning to the heart from the cells, dissolved carbon dioxide.
Red blood cells (also called corpuscles) color the blood. Since there are actually trillions of them circulating in one's body at any one time, their great amount is what gives blood the red color.
As a red blood cell matures, and takes on an adult form in the marrow of the bone, it loses its nucleus and increases its production of hemoglobin. Hemoglobin is the red pigment, or color of blood, and contains iron, combined with protein.
When blood passes through the lungs, oxygen joins the hemoglobin of the red cells. From there, the red cells carry the oxygen through the arteries and the capillaries to all other cells of the body.
Red blood cells stick around for about four months before they are broken up (mostly in the spleen) and then replaced by new red blood cells.
On the contrary, horseshoe crabs have blue blood, which, rather than using hemoglobin, uses a copper containing compound to serve the same purpose.

What color are blood cells when they have on oxygen?
The red blood cells themselves do not take any action to get more oxygen, but the kidneys sense a lack of oxygen and produce more erythropoietin (hormone responsible for producing red blood cells) and this in turn increases oxygen levels
What Color blood cells bring oxygen to cells and take carbon dioxide away?
red blood cell
What color are red blood cells carrying oxygen?
then they are red if they are not carrying oxygen then they are a purple red.
What color blood cells bring oxygen to cells an take carbon dioxide away?
The Red Blood Cells remove wastes from your cells.
What does the stuff do in a red blood cell?
Red blood cells have the important job of picking up oxygen from the lungs and carrying oxygen to all of the other cells of the body. The cells of the body use oxygen as the fuel they need to do their jobs.Red blood cells also give you color. If your skin is white the red blood cells give you the pink color in your skin. They also give your lips a nice pink color.The way we measure the Red Blood Cells is by measuring the Hemoglobin. Hemoglobin is the protein that makes up the Red Blood Cells.When the Hemoglobin level is below 8 grams, the cells of the body do not receive enough oxygen to do their jobs and your body may begin to feel differently.Your heart must also pump harder.
What carries oxygen and gives our blood its color?
Red blood cells.
What carries oxygen and give your blood your color?
Maybe blood cells? :0
What 2 things does hemoglobin in red blood cells do?
Hemoglobin carries the oxygen in the blood and it gives the red blood cells their color.
What is the relationship between oxygen and iron in your body?
Iron and hemoglobin ( a substance found in your red blood cells) combine with oxygen and it turns the blood color from a dark color, to a healthy bright color, also iron picks up oxygen, and carries it through the rest of your body.
What substance carries oxygen and gives blood its color?
haemaglobin
Why does capillary change color as it passes by your body cells?
Capillaries change color as they pass by body cells as the blood they contain loses oxygen. Oxygen-rich blood has a brighter color than oxygen-poor blood.
What color is blood that is not exposed to oxygen?
Human blood has red color when oxygenated which is mainly because of red blood cells. Its color changes to purple when present in oxygen deprived circumstances. To restore the color the blood has to be placed in oxygen rich environment.
What is the color oxyhemoglobin?
Hemoglobin is red while oxyhemoglobin is redder. People think that blood in veins is blue but it has lost the oxygen it was carrying around to the cells so it is a red color but not as red as oxyhemoglobin.
What color are blood cells when they have on oxygen?
The red blood cells themselves do not take any action to get more oxygen, but the kidneys sense a lack of oxygen and produce more erythropoietin (hormone responsible for producing red blood cells) and this in turn increases oxygen levels
What is the name of the complex molecule that carries oxygen in the blood and gives blood its red color?
Hemoglobin.
What color blood cells bring oxygen to cells and take carbon dioxide away.?
the red blood cells
Why does blood change color at the lungs?
Blood changes color at the lungs because it unloads carbon dioxide and absorbs oxygen. Red blood cells that are carrying oxygen are a brighter red color than red blood cells that are depleted of oxygen.
