In humans and other hemoglobin-using creatures, oxygenated blood is bright red. This is due to oxygenated iron in the red blood cells. Deoxygenated blood is a darker shade of red, which can be seen during blood donation and when venous blood samples are taken. However, due to an optical effect caused by the way in which light penetrates through the skin, veins typically appear blue in color. This has led to a common misconception that venous blood is blue before it is exposed to air. Another reason for this misconception is that medical charts always show venous blood as blue in order to distinguish it from arterial blood which is depicted as red on the same chart.
The blood of horseshoe crabs is blue, which is a result of its high content in copper-based hemocyanin instead of the iron-based hemoglobin found, for example, in humans.

Blood has 4 significant elements: Platelets (purple, smaller) a lot less ample, about 13% entire TBV White Blood Cells (Leukocytes) clear yet ought to look white in communities - contain aprx 3% TBV pink Blood Cells (erythrocytes) contain about fifty 5% of TBV Blood is pink, in various shades. quite oxygenated blood is brilliant pink, virtually luminescent in nature, frequently coming direct from the lungs after a huge inhalation of oxygen with techniques from the host body. Depleted blood that has little or no hemoglobin left and is frequently en route decrease back to the middle for refreshments is darkish pink and viscous. in case you opt for to understand what colour 'useless ' blood cells are, ask A coroner, I have not been able to discover that tid-little bit of information. An remoted pink blood cellular without hemoglobin nonetheless is pink, yet a very darkish pink. end - any mammalian crature containing hemoglobin dependant blood has pink blood. that is pink. although---- there's a fish, the Antarctic Ice Fish, that has NO HEMOGLOBIN! no kidding. It dissolves this is oxygen straight away into its tissues and hence has blue blood. tell that to the country golf equipment of Europe! A blue blood, somewhat! LOL

I think all mammals have red blood, at the very least, if not all animals. It has to do with the iron in our red blood cells reacting with oxygen. I guess if other creatures have other elements in their blood that would cause different colours in reacting with oxygen, then their blood wouldn't be red.

The alien in Predator had glowing green blood... I think it was that color because the director wanted it that color... then again I am not an expert on the subject of Predator OR Blood... but all the slasher films seem to be using the color red.

blood is blue until it is mixed with oxygen then it turns red. This is true for the majority of warm blooded creatures.

I know some bivalves have green blood. IIRC, their blood is copper based.
