All you have to do is start with "\e[##m"and end with "\e[0m"
你所要做的就是开始"\e[##m"和结束"\e[0m"
Just replace the ## with the color number. Examples are:
只需用颜色编号替换##。例子是：
31:Red32:Green33:Yellow34:Blue35:Magenta36:Teal37:Grey
31:Red32:Green33:Yellow34:Blue35:Magenta36:Teal37:Grey
1:Bold (Can be used with any color)
1:Bold (Can be used with any color)
Here is a ruby script to show all the terminal colors. Download itor run the code below.

def color(index)
normal = "\e[#{index}m#{index}\e[0m"
bold = "\e[#{index}m\e[1m#{index}\e[0m"
"#{normal} #{bold} "
end
8.times do|index|
line = color(index + 1)
line += color(index + 30)
line += color(index + 90)
line += color(index + 40)
line += color(index + 100)
puts line
end

I am a big fan of the ruby colorize gem, which I recently downloaded. Once you download and include it into your program, you can add
我是最近下载的 ruby colorize gem 的忠实粉丝。下载并将其包含在程序中后，您可以添加
.colorize(:blue)
to the end of any string. You can use most colors, including preceding the color by light_ like so
到任何字符串的末尾。您可以使用大多数颜色，包括在颜色前加上 light_ 像这样
.colorize(:light_blue)
you can also do background colors, EG:
你也可以做背景颜色，EG：
puts "mytext".colorize(:background => :green
colorized underlines, EG:
彩色下划线，EG：
puts "mytext".on_blue.underline
or use HTML-like tags for it as well
或者也使用类似 HTML 的标签
puts <blue> "text text text" </blue>
for the colorize Github, go to The colorize Github
对于着色 Github，请转到着色 Github
you can install the colorize gem by typing
您可以通过键入来安装 colorize gem
gem install colorize
into your terminal, command prompt, whatever. then put this into your file BEFORE YOU PUT IN THE USES OF IT
进入您的终端，命令提示符，等等。然后在您使用它之前将其放入您的文件中
EG:
例如：
require 'rubygems'
require 'colorize'
puts "mytext".colorize(:red)
But NOT
但不是
puts "mytext".colorize(:red)
require 'rubygems'
require 'colorize'
The require statements MUST be in the program in lines BEFORE you use the gem
在使用 gem 之前，require 语句必须在程序中的行中
