This study focuses on the analysis of the cross-modal effects between sight (color) and smell (fragrance). While most previous researches have studied the harmony of color and fragrance using small-field colors such as patches and display stimuli, this study analyzes harmony in lighting environments. In our experiments, we focused on the finding that emotional states manifest themselves in responses in the orbitofrontal cortex and used near-infrared spectroscopy to evaluate orbitofrontal responses. Five different aromas were prepared for fragmentation. Initially, the observers were asked to select the most pleasant and least unpleasant aromas. The two selected aromas were soaked in non-fat cotton cloth and placed in a light-shielding brown bottle, which was used as a scent stimulus. For the lighting environment, 36 different lighting colors were designed using a luminaire consisting of 14 LEDs. The results of the experiment showed that the lighting color that the observers judged to be harmonious by actually smelling the fragrance (sensory color) activated the orbitofrontal cortex more than the lighting color that they judged to be harmonious by recalling the name of the fragrance (imagery color).

本研究重点分析视觉（颜色）和嗅觉（香味）之间的跨模态效应。虽然之前的大多数研究都使用小范围颜色（如补丁和显示刺激）来研究颜色和香味的和谐，但本研究分析了照明环境中的和谐。在我们的实验中，我们专注于发现情绪状态在眶额皮质的反应中表现出来，并使用近红外光谱来评估眶额叶反应。制备了五种不同的香气用于碎裂。最初，观察者被要求选择最令人愉快和最不愉快的香气。将选定的两种香味浸泡在脱脂棉布中，放入遮光的棕色瓶子中，用作香味刺激物。对于照明环境，使用由 14 个 LED 组成的灯具设计了 36 种不同的照明颜色。实验结果表明，观察者通过实际闻到香味判断为和谐的灯光颜色（感官颜色）比他们通过回忆香水名称判断为和谐的灯光颜色（图像）更能激活眶额皮质。颜色）。
