RGB和LAB的区别

SHENMESHIRGB?

人们常常认为颜色都是用RGB来衡量的,就像电脑显示器、电视屏幕的颜色表示方法都是RGB色彩模式,我们甚至可以通过手动调整RGB的参数为计算机上的字体创建自定义的色彩。确实,通过不同RGB的比例,可以混合出自然界中肉眼所能看到的任何色彩。RGB也被称为三基色,其中R就代表红色,选取的就是有红色英文Red的首字母,同样G代表Green(绿色),B代表Blue(蓝色)。RGB模式也被称为RGB色空间,这是一种色光表示的模式,大多数可以发光的设备,都是应用的RGB色彩模式。既然RGB模式使用这么广泛,为什么色差仪检测的颜色参数要用LAB表示而不用RGB表示呢?
