色温及常见光源色温值

光源发射光的颜色与黑体在某一温度下辐射光色相同时，黑体的温度称为该光源的色温。光源色温不同，光色也不同，色温在3300K以下有稳重的气氛，温暖的感觉；色温在3000--5000K为中间色温，有爽快的感觉；色温在5000K以上有冷的感觉。不同光源的不同光色组成最佳环境，如表：

色温                      光色                气氛效果
>5000K                清凉(带蓝的白色)        冷的气氛
3300-5000K            中间(白)                爽快的气氛
<3300K                温暖(带红的白色)        稳重的气氛
 
a. 色温与亮度
高色温光源照射下，如亮度不高则给人们有一种阴气的气氛；低色温光源照射下，亮度过高会给人们有一种闷热感觉。

b. 光色的对比
在同一空间使用两种光色差很大的光源，其对比将会出现层次效果，光色对比大时，在获得亮度层次的同时，又可获得光色的层次。
