- 以命名方式定义常用的颜色,如 RED。
- 以 RGB 值表示,如 #FF0000 表示 red。
命名方式涵括的色种不多亦不甚方便,较少采用,以下介绍 RGB 值的原理:
众所皆知颜色是由 "red" "green" "blue" 三原色组合而成的,在 HTML 中对於彩度的定义是 采十六进位的,对於三原色 HTML 分别给予两个十六进位去定义,也就是每个原色可有 256 种彩度,故此三原色可混合成一千六佰多万的颜色。
例如
白色的组成是 red=ff, green=ff, blue=ff, RGB 值即为 ffffff
红色的组成是 red=ff, green=00, blue=00, RGB 值即为 ff0000
绿色的组成是 red=00, green=ff, blue=00, RGB 值即为 00ff00
蓝色的组成是 red=00, green=00, blue=ff, RGB 值即为 0000ff
黑色的组成是 red=00, green=00, blue=00, RGB 值即为 000000
於应用时常在每个 RGB 值之前加上符号 # 以示分别,但不加亦可。
