RGB颜色(R=红, G=绿, B=蓝)是一种在计算机领域定义数字化颜色的模型,该模型由颜色的红色、绿色、蓝色三种颜色要素构成。

  • R, G , B三种颜色在计算机领域通常的取值范围是0到255,这个取值范围保证三种颜色的每一种颜色值都可以用一个字节来存储。
  • 通过RGB色彩模型,计算机系统可以很容易地调节出任意色彩,但是由于这些数值只说明了每种颜色的百分比,所以它现实中的非计算机领域并不利于人们进行色彩调节。人们经常会说,我要一个更亮的颜色,但是他们并不知道如何把这种颜色转换成RGB三色数值。因此,人们就发明了一种更加接近自然调色方式的配色系统HSB,使得人们在计算机上可以自然地调节颜色。
