参考
\e an ASCII escape character (033)
颜色设置开始 \033[31m 或者\e[31m
恢复设置前颜色 \033[0m 或者\e[0m
其中“[”后面整数31表示修改字符颜色红色
可以设置背景颜色和字符高亮/下划线等,写多个颜色设置即可
如\033[0;31m\033[44m 蓝底红字
echo -e "\033[0;31m\033[44mhello\033[0m" 蓝底红字的"hello"
echo -e "\033[0;31m\033[44m\033[4mhello\033[0m" 蓝底亮红字的"hello"
Black 0;30 Dark Gray 1;30
Blue 0;34 Light Blue 1;34
Green 0;32 Light Green 1;32
Cyan 0;36 Light Cyan 1;36
Red 0;31 Light Red 1;31
Purple 0;35 Light Purple 1;35

下面这个脚本可以打印颜色代码,执行一下挑选喜欢的颜色,很不错
#!/bin/bash
#
# This file echoes a bunch of color codes to the
# terminal to demonstrate what's available. Each
# line is the color code of one forground color,
# out of 17 (default + 16 escapes), followed by a
# test use of that color on all nine background
# colors (default + 8 escapes).
#
T='gYw' # The test text
echo -e "\n 40m 41m 42m 43m\
44m 45m 46m 47m";
for FGs in ' m' ' 1m' ' 30m' '1;30m' ' 31m' '1;31m' ' 32m' \
'1;32m' ' 33m' '1;33m' ' 34m' '1;34m' ' 35m' '1;35m' \
' 36m' '1;36m' ' 37m' '1;37m';
do FG=${FGs// /}
echo -en " $FGs \033[$FG $T "
for BG in 40m 41m 42m 43m 44m 45m 46m 47m;
do echo -en "$EINS \033[$FG\033[$BG $T \033[0m";
done
