如何在Golang SSH客户端中删除颜色代码

I am using golang ssh package to build a ssh client, I set the terminal modes as below

// Set up terminal modes
modes := ssh.TerminalModes{
    ssh.ECHO:          0,     // disable echoing
    ssh.TTY_OP_ISPEED: 14400, // input speed = 14.4kbaud
    ssh.TTY_OP_OSPEED: 14400, // output speed = 14.4kbaud
}

// Request pseudo terminal
if err := session.RequestPty("xterm", 80, 40, modes); err != nil {
    log.Fatalf("request for pseudo terminal failed: %s", err)
}

it works fine, but a tiny problem, when I use "ls" command, it returns the names with color code, like below

[root@localhost ~]# ls
ls
anaconda-ks.cfg    [0m[01;34mpeter[0m
[01;32mbuild.sh[0m           [01;34mredis64[0m

it makes me feel difficult to read the file names, so is there any method to remove the color code around the names? thanks

Use session.RequestPty with "vt220" terminal type

example: session.RequestPty("vt220", 80, 40, modes)
