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
When blood cells have oxygen they are red, when they have no oxygen they are a darker shade of red.
blue color
red blood cell
then they are red if they are not carrying oxygen then they are a purple red.
The Red Blood Cells remove wastes from your 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.

red blood cell
Hemoglobin carries the oxygen in the blood and it gives the red blood cells their color.
When blood cells have oxygen they are red, when they have no oxygen they are a darker shade of red.
then they are red if they are not carrying oxygen then they are a purple red.
