Darth Vader's blood

"Blood is about to spill, all right. Yours!"
General Grievous, to Maul[1]

Blood was a liquid substance present in most sentient beings, though not all species had the same color of blood. Humans[2], Aqualish[3] and Iktotchi,[4] for example, had red blood; while Rodians,[5] Duros,[6] Trandoshans,[7], Lokori,[8] and some Pykes had green blood.[9] Other Pykes instead possessed yellow blood[10] as did Geonosians.[11] Kiffar had scarlet blood,[12] Devaronians had black blood[13] and Anzellans had purple blood.[14]

By testing a sample of someone's blood, it was possible to get a midi-chlorian count and determine how sensitive one was to the Force.[15] Human blood was said to have a characteristic metallic taste.[16] Bloodburn was a rare blood disease that affected some starship pilots.[17]

The emotions of sentient beings of flesh and blood were driven by chemicals in their bloodstream. However, stone-based beings who had no blood, such as the Kakran, processed information differently and did not experience strong emotions, such as fear.[18]
