Answer 1

1.没明白，你是想要完整的不用独立去除的话
{\\colortbl\s*;(?<color>\\red[^;]+;)+}
2.空格也要
\\cf[^ ]+(.+?)(?=\\par|})    private static void TestRegex22()
    {
        string a = @"{\rtf1\ansi\ansicpg936\deff0\deflang1033\deflangfe2052{\fonttbl{\f0\fmodern\fprq6\fcharset134 \'cb\'ce\'cc\'e5;}{\f1\fnil ;}{\f2\fnil\fcharset134 \'b7\'bd\'d5\'fd\'d2\'a6\'cc\'e5;}{\f3\fnil\fcharset134 \'b7\'bd\'d5\'fd\'ca\'e6\'cc\'e5;}{\f4\fnil\fcharset134 \'bf\'ac\'cc\'e5_GB2312;}{\f5\fnil\fcharset134 \'c1\'a5\'ca\'e9;}{\f6\fnil\fcharset134 \'ba\'da\'cc\'e5;}{\f7\fswiss\fcharset0 Arial;}}

Answer 2

是取 {\colortbl ;\red0\green0\blue0;\red0\green255\blue255;\red0\green0\blue255;\red138\green43\blue226;\red165\green42\blue42;\red169\green169\blue169;\red255\green0\blue0;\red0\green255\blue0;\red255\green255\blue0;}  中的 “\red0\green0\blue0”  “\red0\green255\blue255” ... 我是怕 别的地方 还会有类似这样 那取出来 就坏了...

内容中有\没关系，不要有\par就成。
