What gives blood its red color?
2 doctors weighed in across 2 answers
Hemoglobin: Hemoglobin is the molecule than contains iron and carries oxygen from the lungs to all parts of the body. Hemoglobin is red, and fills up the red blood cells, thus making the cells look red.

Hemoglobin: This is a simple question and already answered. Hemoglobin, the oxygen carrying molecules in your blood provide this color when oxygen is attached to the molecule.
