希望增加背景色功能



一下脚本代码和“自动无缝翻页”脚本有冲突，用了此护眼脚本发现没有更改背景色功能

// ==UserScript==
// @name 护眼脚本
// @namespace http：//www.houhongwei.xyz
// @description 修改网页背景色，让网页背景色偏白的部分变成乡土黄、豆沙绿，浅色灰还有淡橄榄，更加护眼。默认护眼色是乡土黄。

//当网页的背景颜色的rgb值分别大于Gr1,Gg1,Gb1时此脚本将把颜色改成目标颜色color
var Gr1 = 242; //RGB中的R值
var Gg1 = 242; //RGB中的G值
var Gb1 = 242; //RGB中的B值

//**********以下代码用户无需修改***********//
var Gr, Gg, Gb; //全局变量记录当前标签的rgb值,用于比较

//以下函数用于分解获取的"rgb(255, 255, 255)"格式的rgb
