Human flatulence, thermogram. Intestinal gas (red, lower left) being expelled from the body. The gas shows up as red because it has recently been at body temperature, which is warmer than the surroundings. The colour-coded heat display here runs from purple and blue (coolest) through green and yellow, to red and white (hottest).
