The color of human blood ranges from bright red when oxygenated to a darker red when deoxygenated. [2] It owes its color to hemoglobin, to which oxygen binds. Deoxygenated blood is darker due to the difference in shape of the red blood cell when oxygen binds to haemoglobin in the blood cell (oxygenated) versus does not bind to it (deoxygenated).
The colour blood red is a dark shade of the colour red meant to resemble the colour of human blood (which is composed of oxygenated red erythrocytes, white leukocytes, and yellow blood plasma). [2] It is the iron in hemoglobin specifically that gives blood its red colour. The actual colour ranges from crimson to a dark brown-blood depending on ...
Arterial blood is the oxygenated blood in the circulatory system found in the pulmonary vein, the left chambers of the heart, and in the arteries. [1] It is bright red in color, while venous blood is dark red in color (but looks purple through the translucent skin). It is the contralateral term to venous blood. [citation needed]
Wright's stain is a hematologic stain that facilitates the differentiation of blood cell types. It is classically a mixture of eosin (red) and methylene blue dyes. It is used primarily to stain peripheral blood smears, urine samples, and bone marrow aspirates, which are examined under a light microscope.
The color of blood red ranges from crimson to a dark brown-red and may have a slightly orange hue. In the RGB color spectrum, it often consists only of the color red, with no green or blue component; in the CMYK color model blood red has no cyan, and consists only of magenta and yellow with a small amount of black.

Mature red blood cells lack a nucleus and organelles in mammals. The red blood cells (together with endothelial vessel cells and other cells) are also marked by glycoproteins that define the different blood types. The proportion of blood occupied by red blood cells is referred to as the hematocrit, and is normally about 45%. The combined ...
Sanguine (/ ˈ s æ ŋ ɡ w ɪ n /) is a stain, or non-standard tincture in heraldry, of a blood-red colour. In the past it was sometimes taken to be equivalent to murrey, [1] but they are now considered two distinct tinctures. It is a darker red, the colour of arterial blood. [2]
