Yes but in different conditions:
Firstly when there is no oxygen (as blood from veins) hemoglobin turns darker red, that means the oxygen pays an important role in this situation.
On the other hand, the appearance of blood as darker blue is a wavelengh phenomenon of light, having to do with the reflection of blue light away from the outside of venous tissue if the vein is ~ 0.02 inches deep ormore.

Why does the blood become more darker as it is being pumped round the body?
As blood travels through the body, it delivers oxygen to tissues and organs. Oxygenated blood is bright red, but as oxygen is utilized, the blood becomes deoxygenated and appears darker. This change in color is a result of the oxygen-rich hemoglobin turning into deoxygenated hemoglobin.
How do red blood cells make more space for hemoglobin?
They do not have a nucleus which allows them to make more space for haemoglobin.
Why is De-oxygenated blood darker red?
Well, honey, de-oxygenated blood is darker red because it doesn't have any oxygen in it. Oxygen-rich blood is bright red, like a cherry on top of a sundae, while de-oxygenated blood is more like a sad, wilted rose. So, when your blood is feeling blue and lacking oxygen, it's gonna look darker because it's missing that vibrant red color.
When oxygen is lost from hemoglobin the colour of the blood changes?
When oxygen is lost from hemoglobin, the blood appears darker and more purplish in color. This deoxygenated blood returns to the heart and then to the lungs to pick up more oxygen before circulating throughout the body again.
What substance causes red blood cells to change coloour?
Hemoglobin changes color according to what it is bound to. When it is oxygenated, it is closer to bright red. When it is carrying carbon dioxide, it is darker red or brown. When it is carrying carbon monoxide, it is also quite bright red.
What system does hemoglobin belong to?
The circulation system in the body contains hemoglobin, more specifically the blood.
Name the substance in red blood cells that combines with oxygen?
The protein "Hemoglobin" is responsible for the red color. Each hemoglobin molecule can bind up to 4 oxygen atoms. When fully loaded with oxygen atoms the protein takes on a more bright red color. When deprived of oxygen the protein takes on a darker red/blue color.
More than 95 percent of the protein in a red blood cell is?
More than 95 percent of the protein in a red blood cell is hemoglobin. Hemoglobin is a protein that binds to oxygen and transports it throughout the body.
What is hemoglobin carry to the cell?
Hemoglobin carries oxygen to the body's tissues. It is found in erythrocytes.
Do red blood cells have more hemoglobin than white blood cells?
Yes! All red blood cells are only hemoglobin encased in a membrane. White blood cells do not carry much hemoglobin, becasue they have every other organelle like the ER, nucleus, and golgi apparatus to name a few. Red blood cells don't even have a nucleus! Their sole purpose is to give hemoglobin to the blood. When red blood cells are being made in the marrow, they have organelles but once they are mature, everything is taken out and they become hemoglobin carriers, with nothing else. So finally, red blood cells have much more hemoglobin than white blood cells.
How much will your hemoglobin increase after 1 unit of blood?
by 3 times more
What do the red blood cells contain?
Red blood cells contain hemoglobin, a protein that carries oxygen from the lungs to the rest of the body. Hemoglobin also helps carry carbon dioxide back to the lungs to be exhaled. Red blood cells do not have a nucleus, allowing them to have more space to carry oxygen.
