原色(基本色)的基础知识

原色是指不能通过其他颜色的混合调配而得出的“基本色”。它们是RGB(红绿蓝)。RGB 色系也是我们常说的加色法,混合任两个原色,就会产生三个次原色:青、洋(品)红。RGB这三种颜色的组合,几乎形成了所有的颜色。将光的三原色加在一起就可以做出白光。所以,如果一个 RGB 的值为 255,255,255 则表示为白色。如果完全拿掉这三原色的光 (RGB: 0,0,0) 则产生黑色。

RGB 模式的相反模式就是 CMYK 模式也就是减色法,CMYK模式中所使用的三原色就是 RGB 模式中的次颜色。如果将红、绿、蓝光混合在一起形成白光,那么就表示将青、洋红、黄三色的颜料混合在一起就会产生黑色,因为三原色的光波都将被颜料所吸收了。
