Facial expressions of emotion contain important information that is perceived and used by observers to understand others' emotional state. While there has been considerable research into perceptions of facial musculature and emotion, less work has been conducted to understand perceptions of facial coloration and emotion. The current research examined emotion-color associations in the context of the face. Across four experiments, participants were asked to manipulate the color of face, or shape, stimuli along two color axes (i.e., red-green, yellow-blue) for six target emotions (i.e., anger, disgust, fear, happiness, sadness, surprise). The results yielded a pattern that is consistent with physiological and psychological models of emotion.Keywords: Emotion, Color, Face, Association
EMOTION-COLOR ASSOCIATIONS
3Outward expressions of emotion convey information about an individual's internal physiological and psychological state. Perceptual expectations regarding emotion are generated and reinforced through continued interactions with others. Specifically, perceivable characteristics of emotion are detected and stored as information, which is later used to effectively predict and understand others' emotion (Jack, Garrod, & Schyns, 2013;Yuille & Kersten, 2006). These expectations therefore reflect deeply engrained emotion-perception associations. By studying these associations, we can understand how emotion information is transmitted and interpreted as social information.An important, yet understudied property of emotion expression is facial coloration. While a substantial amount of research on emotion expression has been dedicated to investigating facial musculature (Ekman, 1993), very little empirical work has been conducted to examine the role of facial coloration changes in emotion communication. However, facial coloration reflects physiological and psychological processes that are biologically and socially relevant. For example, facial color has been shown to influence perceptions of health (Stephen, Coetzee, Law Smith, & Perrett, 2009;Young, Thorstenson, & Pazda, 2016), attractiveness (Jones, Little, Burt, & Perrett, 2004;Thorstenson, Pazda, Elliot, & Perrett, 2016), and personality (Stephen, Oldham, Perrett, & Barton, 2012). Further, because the expression of emotion cues is an important component of emotion communication (Keltner & Haidt, 1999), we should expect to find cognitive and perceptual mechanisms that facilitate detecting such cues to emotion in others (Phelps, Ling, & Carrasco, 2006). In line with this, there is evidence that trichromatic color vision in humans is well suited, even optimized, for detecting subtle skin color changes resulting from physiological processes (Changizi, Zhang, & Shimojo, 2006; Lefevre, Ewbank, Calder,
