Color therapy, healing through color, supposedly works through the physical exposure to color. In two studies, we assessed stress and anxiety reduction after color exposure using a commercially available relaxation‐through‐color routine. Participants either completed the routine by looking at the accompanying color disks or at a white patch. In study 1 (longitudinal), 60 participants completed the routine three times, each testing session separated by a week. In study 2 (cross‐sectional), 63 participants completed half of the trials once. In both studies, we recorded a decrease in stress and anxiety levels comparing before‐after scores. In study 1, we recorded incremental decreases with each week. Crucially, decreases were the same whether participants (a) physically saw colors or not, and (b) completed the full or shortened version. We conclude that other factors but physical exposure to color explain changes in affective states associated with this and probably other color therapy routines.

看或不看：色彩感知对色彩疗法的重要性

色彩疗法可以通过色彩治愈，据说可以通过物理暴露于色彩来起作用。在两项研究中，我们使用市售的“通透色彩”程序评估了色彩暴露后压力和焦虑的减轻。参与者可以通过查看随附的彩色光盘或白色补丁来完成例程。在研究1（纵向）中，有60名参与者完成了3次常规程序，每个测试阶段间隔一周。在研究2（横断面）中，有63名参与者完成了一半的试验。在两项研究中，我们都记录了前后得分相比，压力和焦虑水平的降低。在研究1中，我们记录了每周的增量减少。至关重要的是，无论参与者（a）物理上是否看到颜色，以及（b）完成完整版或缩短版，参与者的减少幅度都是相同的。
