What Color Is Blood. Venous blood (except in the pulmonary veins) is low in oxygen so the hemoglobin makes the blood have a dark red color. Once the blood has passed through the capillary beds of the lungs, the blood will be bright red with the hemoglobin saturated with oxygen gas.
However, red is not the only blood colour available â it also comes in blue, green, violet, and even colourless varieties â and this is a result of the specific chemicals that make up blood in different organisms. So, letâs start with what we already know. Most people will have learnt that human blood, as well as that of most other vertebrates, is red as a result of haemoglobin, a large protein found in red blood cells which contains iron atoms within its structure.
