This study examined whether people's ability to recognize facial expressions is affected by manipulating the color of their lips or eyes. Participants comprised 100 Chinese adolescents (mean age = 13.79 years, SD = 1.06). The stimuli consisted of happy, neutral, and sad facial expressions, which were manipulated to have different lip or eye colors. Participants reacted to the images by indicating their perceived emotion. Performance speed and accuracy were assessed during the experiment. Results indicated that for happy and neutral expressions, the use of color significantly reduced reaction times, while the accuracy remained unchanged. Conversely, for sad expressions, reaction time was not affected by color, but all color categories exhibited reduced accuracy. Facial expression image samples (blurred version) included (A) pink mouth (original neutral face), (B) blue mouth (neutral face), (C) orange mouth (neutral face), (D) purple mouth (neutral face), (E) red mouth (neutral face), (F) brown eyes (original sad face), (G) blue eyes (sad face), (H) green eyes (sad face), and (I) red eyes (sad face). The bottom row shows mean a*b value for lip and eye color across three individuals. Error bars represent the standard deviation from the mean color values across three individuals; The arrows indicate the general trend from original color photographs towards manipulated color variations.image
