Oxygen in liquid form is very pale blue.
Blood is actually red due to the presence of hemoglobin, a protein that contains iron and binds with oxygen. When blood is oxygen-rich, it appears bright red, while oxygen-poor blood appears darker red. The misconception that blood is blue comes from the color of veins, which can appear blue under the skin due to how light interacts with it.
Blood only appears blue when viewed through the skin because of the way light interacts with it. Oxygen-rich blood is bright red and oxygen-poor blood is a darker red color. The blue hue seen under the skin is due to light absorption and scattering, not the actual color of the blood.
Red color in acidic solutions and blue color in basic solutions.
Blue is a primary color, red and blue mixed make the secondary color purple.
The color between blue and red is purple. It is a secondary color formed by mixing blue and red together.
When blood cells have oxygen they are red, when they have no oxygen they are a darker shade of red.
Human blood has red color when oxygenated which is mainly because of red blood cells. Its color changes to purple when present in oxygen deprived circumstances. To restore the color the blood has to be placed in oxygen rich environment.
Hemoglobin is red in color when it is carrying oxygen.
I THINK that blue is used because it is the color of blood without oxygen and red is used because it is the color of blood with oxygen. Also look at your veins see what color they are.
red and blue
Your father probably has chronic obstructive pulmonary disease. A difficulty in the oxygen being delivered from the lungs to the red blood cells in his blood. Thus the hemoglobin in his red blood cells are not all filled with oxygen. Hemoglobin, if unfilled with oxygen, changes from a red color to a deep blue/purple color. That is why we think of blood coming from the heart as red and returning to the heart as blue on diagrams of the circulatory system. In fact, if your father was not on oxygen, his nails probably would be an even darker blue color. The oxygen should be, in fact, improving his color.
Well, when it is in your body it is blue. When it hits oxygen it turns red.
Hemoglobin, when united with oxygen, turns bright red.
Oxygen has hit the bood. Although the true color of blood is blue, when blood is exposed to oxygen it turns red.

Blue. Your blood is always blue until it is exposed to oxygen, when it reacts and turns red. Since veins aren't exposed to air/oxygen, they remain blue :)
That's easy. When blood is in your body it is blue that's why your veins are blue. When oxygen meets the blood the blood turns red.
