Have you ever tried to hide your emotions （情感）from someone during a conversation？ （1）
Scientists from the Ohio State University have found that people are able to tell other people's emotions according to changes in the color of their faces．
Scientists studied pictures of people's facial expressions． （2） For example， happiness makes our faces red around the cheeks and a little blue around the chin． Disgust（厌恶）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（触发） by the central nervous（神经） system．" Lead researcher Alex Martinez said．
（3） Does the color alone or also facial expressions help people tell other's emotions？
To figure this out， scientists added color patterns to pictures of faces that showed no facial expressions． （4） They were able to tell the emotions 75 percent of the time without any difficulty．

A． But this raises a question．
B． It is shown that human emotions are influenced by colors on the face．
C． They found that every facial expression is connected to a certain color．
D． It's not always easy， because the color on your face may tell the truth．
E． Then， volunteers were asked to tell what emotions the faces were showing．
F． This is why there are some Chinese sayings that connect emotions to the color of one's face．
