This study investigates the relationship between color perception-hue, brightness, and saturation-and its emotional response-valence, arousal, and pleasure-, through subjective evaluations, as well as their association with frontal and parietal asymmetric activity patterns through electroencephalographic (EEG) recording. Using the 37 colors from the Berkeley Color Project, along with positive and negative control images, we examined the perceptual and emotional dimensions of color in 32 Mexican participants (19 women; M = 21.4 years, SD = 3.3). Subjective evaluations revealed a strong positive correlation between valence and brightness, and between arousal and saturation. Brighter, arousing, and pleasant colors were associated with greater cortical activation (decreased alpha power) in the left dorsolateral prefrontal region-i.e., F3 electrode-, indicating positive emotional processing according to the frontal alpha asymmetry model. Additionally, increased theta power in the right lateral parietal region-i.e., P4 electrode-correlated with higher positive emotional and pleasurable responses. Our findings are in line with studies suggesting universal consistencies in how perceptual color dimensions relate to emotional responses. Moreover, significant correlations between subjective emotional responses and asymmetrical EEG activity models are highlighted, providing insights into the neural mechanisms of color-induced emotion perception, as no other study has done before to our knowledge. Further research should explore these associations using higher spatial resolution imaging techniques and larger electrode arrays to define precise cortical and subcortical regions involved. These results contribute to understanding color perception's impact on emotions, with potential applications in mental health treatments, such as chromotherapy for mood disorders.
本研究通过主观评估，以及通过脑电图 (EEG) 记录研究颜色感知（色调、亮度和饱和度）与其情绪反应（效价、唤醒和愉悦）之间的关系，以及它们与额极和顶叶不对称活动模式的关联。使用伯克利颜色项目的 37 种颜色，以及正、负对照图像，我们研究了 32 名墨西哥参与者（19 名女性；M=21.4 岁，SD=3.3）对颜色的感知和情绪维度。主观评估显示，效价和亮度之间，以及唤醒和饱和度之间存在很强的正相关。更亮、更令人兴奋和更愉快的颜色与左背外侧前额叶区域（即 F3 电极）的皮质激活增加（alpha 功率降低）相关，根据额叶 alpha 不对称模型表明正性情绪处理。此外，右外侧顶叶区域（即 P4 电极）的 theta 功率增加与更高的正性情绪和愉悦反应相关。我们的研究结果与表明感知颜色维度与情绪反应之间存在普遍一致性的研究一致。此外，强调了主观情绪反应与不对称 EEG 活动模型之间的显著相关性，为颜色引起的情绪感知的神经机制提供了深入的了解，据我们所知，之前没有其他研究这样做过。进一步的研究应该使用更高空间分辨率的成像技术和更大的电极阵列来探索这些关联，以定义涉及的精确皮质和皮质下区域。这些结果有助于理解颜色感知对情绪的影响，在心理健康治疗（如情绪障碍的色彩疗法）方面具有潜在的应用。
