比如zshrc
加入然后重启iterm2

if [[ -n "$ITERM_SESSION_ID" ]]; then
    tab-color() {
        echo -ne "\033]6;1;bg;red;brightness;$1\a"
        echo -ne "\033]6;1;bg;green;brightness;$2\a"
        echo -ne "\033]6;1;bg;blue;brightness;$3\a"
    }
    tab-red() { tab-color 255 0 0 }
    tab-green() { tab-color 0 255 0 }
    tab-blue() { tab-color 0 0 255 }
    tab-reset() { echo -ne "\033]6;1;bg;*;default\a" }

    function iterm2_tab_precmd() {
        tab-reset
    }

    function iterm2_tab_preexec() {
        if [[ "$1" =~ "^ssh " ]]; then
            if [[ "$1" =~ "prod" ]]; then
                tab-color 255 160 160
            else
                if [[ "$1" =~ "staging" ]]; then
                    tab-color 255 204 153
                else
                fi
            fi
        else
            if [[ "$1" =~ "auth" ]]; then
                tab-color 255 178 102
            else
                if [[ "$1" =~ "cv" ]]; then
                    tab-color 204 255 229
                else
                    tab-color 204 204 255
                fi
            fi
        fi
    }

    autoload -U add-zsh-hook
    # 注释了默认颜色
    #add-zsh-hook precmd  iterm2_tab_precmd
    add-zsh-hook preexec iterm2_tab_preexec
fi

是根据标题文本匹配的颜色 自己可以改规则改颜色
