Why does blood have a light yellow color?
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.
What is the real true color of blood?
The “color” of blood depends on how much oxygen is in the blood; when here is plenty of oxygen, the blood is more “reddish in color. The reason that this is so is because of a protein called HEMOGLOBIN, which carries the oxygen in your blood. When hemoglobin has a full oxygen load, it gives the blood a reddish color.
What carries oxygen and give blood its color?

What color is blood before it leaves your body?
Blood in the human body is red regardless of how oxygen-rich it is, but the shade of red may vary. The level or amount of oxygen in the blood determines the hue of red. As blood leaves the heart and is oxygen-rich, it is bright red. When the blood returns to the heart, it has less oxygen. It is still red but will be darker.
