原因在于,人眼所能见到的光频谱落在可见光范围(约400~700NM波长),眼睛能感知颜色主要凭借锥细胞,锥细胞内含蓝绿红三种视光素。绿光的波长同时落在蓝绿红三种视光素吸收光谱的波峰下缘(亦即三种视光素所受到的总和刺激感应较少),所以也就达到"休息"的效果了。

各种颜色对光线的吸收和反射是各不相同的,红色对光线反射是67%,黄色反射是65%,绿色反射是47%,青色只反射36%。由于红色和黄色对光线反射比较强,因此容易产生耀光而刺眼。青色和绿色对光线的吸收和反射都比较适中,所以对人体的神经系统、大脑皮层和眼睛里的视网膜组织比较适应。比如,青草和绿色,不仅能吸收强光中对眼睛有害的紫外线,同时还能减少因强光对眼睛所产生的耀光。
