Have you ever tried to hide your emotions from someone during a conversation？? ? ? ?1

Scientists from the Ohio State University have found that people are able to tell other peoples emotions according to changes in the color of their faces.

Scientists studied pictures of peoples facial expressions.

2? ? ? ?For example， happiness makes our faces red around the cheeks and a little blue around the chin. Disgust（厭惡）creates not only a blue-yellow color around the lips， but also a red-green color around the nose and forehead.

“We believe these color patterns are the result of small changes in blood flow triggered（觸發(fā)） by the central nervous（神經(jīng)） system.” Lead researcher Alex Martinez said.
