Hemoglobin is a complex protein carried by erythrocytes (red blood cells). Hemoglobin transports oxygen from the respiratory organ(s) to the cells, and carbon dioxide from the cells to the respiratory organ(s). Because hemoglobin contains iron, and iron, when combined with oxygen, demonstrates a characteristic red color, hemoglobin causes blood to appear red (oxygenated blood is bright red, deoxygenated blood is a dark red, sometimes with a bluish hue). Because hemoglobin appears red, it can cause skin color to appear reddish or flushed/blushed (erythematic). As it breaks down, hemoglobin loses its reddish color and may instead appear blue, yellow, brown, purple, or even black. This is why bruises initially appear red, but then may change colors.
Hemoglobin does nothing to skin color. But it is "malanin" that gives skin color. And hemoglobin gives red color to the blood in case of human beings.
the more oxygen the redder the blood
most would be hemoglobin
melanin and caroteneB:Skin color is determined by the relative presence of Melanin pigment, Carotene pigment and the extent to which the blood is oxygenated
Psychological factors like stress, anxiety, and mood can influence skin color through the release of hormones like cortisol, which can impact melanin production. Additionally, psychological conditions like depression can affect blood flow to the skin, leading to changes in skin tone. Lastly, lifestyle factors associated with psychological well-being, such as diet and sleep, can also play a role in maintaining healthy skin color.
Yes it is! And Melanin is responsible for the skin of dark-skinned people.
It highly depend on the circumstance. Some bacteria will destroy the hemoglobin, and thus the hemolyzed blood appears transparents, whereas other process will only destroy the hemoglobin wall and thus liberating the hemoglobin, which is then pale cherry roughly in color.
By: Ms. Embalmer21: The red pigmintation is from the Hemoglobin and Oxyhemoglobin. Because think about it. One of the choices is melanin. Well melanin is the derterminant of your skin color. Black, White, or whatever. And carotene, is an orange color. Well, orange isn't red. So, by process of elimination, it has to be hemoglobin and oxyhemoglobin.

Bright red
The color is bluish-brown.
Skin color has to do with the amount of melanin that a person produces, which generally corresponds to the climate that their ancestors originated from. Generally, peoples from regions closer to the equator have darker skin and those farther from it have lighter skin. Ultraviolet B radiation increases the production of melanin by melanocytes, so that both genetics and environment influence skin color.
No, hemoglobin is found predominantly in blood. The stratum corneum is avascular, and hemoglobin is not predominant in this skin layer.
Hemoglobin makes cells red since it has iron in it.
