这是我过去看到的所有组合，并决定哪一个读起来很酷：

for (( i = 0; i < 8; i++ )); do
    for (( j = 0; j < 8; j++ )); do
        printf "$(tput setab $i)$(tput setaf $j)(b=$i, f=$j)$(tput sgr0)\n"
    done
done

这是颜色开关\033[。请参阅历史记录。

颜色代码类似于1；32（浅绿色），0；34（蓝色），1；34（浅蓝色）等。

我们使用颜色开关\033[和0m（无颜色代码）终止颜色序列。就像标记语言中的打开和关闭选项卡一样。

  SWITCH="\033["
  NORMAL="${SWITCH}0m"
  YELLOW="${SWITCH}1;33m"
  echo "${YELLOW}hello, yellow${NORMAL}"

简单的彩色回声功能解决方案：

cecho() {
  local code="\033["
  case "$1" in
    black  | bk) color="${code}0;30m";;
    red    |  r) color="${code}1;31m";;
    green  |  g) color="${code}1;32m";;
    yellow |  y) color="${code}1;33m";;
    blue   |  b) color="${code}1;34m";;
    purple |  p) color="${code}1;35m";;
    cyan   |  c) color="${code}1;36m";;
    gray   | gr) color="${code}0;37m";;
    *) local text="$1"
  esac
  [ -z "$text" ] && local text="$color$2${code}0m"
  echo "$text"
}

cecho "Normal"
cecho y "Yellow!"

我用这个做彩色印刷

所有的基本颜色都设置为vars，还有一些有用的函数：XY、line和que。将此脚本源于您的一个脚本，并使用所有颜色vars和函数。

您可以“组合”颜色和文本模式。

后果

希望这张图片能帮助你选择适合你的颜色：D

这些代码在我的Ubuntu盒子上运行：

echo -e "\x1B[31m foobar \x1B[0m"
echo -e "\x1B[32m foobar \x1B[0m"
echo -e "\x1B[96m foobar \x1B[0m"
echo -e "\x1B[01;96m foobar \x1B[0m"
echo -e "\x1B[01;95m foobar \x1B[0m"
echo -e "\x1B[01;94m foobar \x1B[0m"
echo -e "\x1B[01;93m foobar \x1B[0m"
echo -e "\x1B[01;91m foobar \x1B[0m"
echo -e "\x1B[01;90m foobar \x1B[0m"
echo -e "\x1B[01;89m foobar \x1B[0m"
echo -e "\x1B[01;36m foobar \x1B[0m"

这将以不同的颜色打印字母a、b、c、d：

echo -e "\x1B[0;93m a \x1B[0m b \x1B[0;92m c \x1B[0;93m d \x1B[0;94m"

对于循环：

for (( i = 0; i < 17; i++ )); 
do echo "$(tput setaf $i)This is ($i) $(tput sgr0)"; 
done
