If your rxvt has 256 colors enabled, you can use extended color codes (e.g. "^[[38;5;36m"). Try this script to test if your terminal has 256 colors enabled. Probably you need to patch/recompile it or download another version. I recommend this tutorial.
You're using an ANSI escape sequence, which has very limited color options. I use an .Xdefaults file (explained in this tutorial). These options won't make your shell prompt all colorful, but is used by editors such as vim.
Be aware that .Xdefaults can be picky about UNIX (CR) vs Windows (CRLF) line endings. Use d2u or u2d to switch line endings as necessary.

如果您的 rxvt 启用了 256 种颜色，您可以使用扩展颜色代码（例如“^[[38;5;36m”）。 试试这个 脚本 来测试您的终端是否启用了 256 种颜色。 可能您需要修补/重新编译它或下载另一个版本。 我推荐这个教程。

您使用的是 ANSI 转义序列，其颜色选项非常有限。 我使用 .Xdefaults 文件（本教程中进行了说明）。 这些选项不会使您的 shell 提示符变得丰富多彩，但可供 vim 等编辑器使用。
请注意，.Xdefaults 对 UNIX (CR) 与 Windows (CRLF) 行结尾可能很挑剔。 根据需要使用 d2u 或 u2d 切换行结尾。
