RGB色彩模式是工业界的一种颜色标准，是通过对红(R)、绿(G)、蓝(B)三个颜色通道的变化以及它们相互之间的叠加来得到各式各样的颜色，RGB即是代表红、绿、蓝三个通道的颜色，标准RGB颜色查询对照表几乎包括了人类视力所能感知的所有颜色，是运用最广的颜色系统之一。



由于网页(web)是基于计算机浏览器开发的媒体，所以颜色以光学颜色RGB（红、绿、蓝）为主。网页颜色是以16进制代码表示，一般格式为#DEFABC （字母范围从A-F,数字从0-9 ）；如黑色，在网页代码中便是：#000000(在CSS编写中可简写为#000)。当颜色代码为#AABB11时，可以简写为#AB1表示，如#135与#113355表示同样的颜色。

RGB是一种颜色显示模式的三原色，通常情况下，RGB各有256级亮度，用数字表示为从0、1、2...直到255，共256级。三种颜色不同亮度的组合可以构成形形色色的颜色，详细请看以下RGB颜色查询对照表：
