我想用不同的颜色打印一行。

使用ANSI转义序列。

Windows 10之前-在控制台上不支持ANSI颜色

对于低于10的Windows版本，Windows命令控制台默认情况下不支持输出着色。您可以安装Cmder, ConEmu, ANSICON或Mintty(在GitBash和Cygwin中默认使用)来为Windows命令控制台添加着色支持。

Windows 10 -命令行颜色

从Windows 10开始，Windows控制台默认支持ANSI转义序列和一些颜色。该功能于2015年11月随Threshold 2更新一起发布。

MSDN文档

更新(05-2019):ColorTool允许您更改控制台的配色方案。这是微软终端项目的一部分。

在powershell中为日志语句设置颜色并不是什么大问题。 你可以使用-ForegroundColor参数。

写一个确认消息。

Write-Host "Process executed Successfully...." -ForegroundColor Magenta

写入错误消息。

Write-Host "Sorry an unexpected error occurred.." -ForegroundColor Red

写一个进度消息。

Write-Host "Working under pocess..." -ForegroundColor Green

您可以用要打印的单词的名称创建文件，使用findstr(可以彩色打印)，然后擦除该文件。试试这个例子:

@echo off
SETLOCAL EnableDelayedExpansion
for /F "tokens=1,2 delims=#" %%a in ('"prompt #$H#$E# & echo on & for %%b in (1) do rem"') do (
  set "DEL=%%a"
)

call :ColorText 0a "green"
call :ColorText 0C "red"
call :ColorText 0b "cyan"
echo(
call :ColorText 19 "blue"
call :ColorText 2F "white"
call :ColorText 4e "yellow"

goto :eof

:ColorText
echo off
<nul set /p ".=%DEL%" > "%~2"
findstr /v /a:%1 /R "^$" "%~2" nul
del "%~2" > nul 2>&1
goto :eof

运行color /?得到一个颜色列表。

最简单的方法是像这样对powershell进行系统调用:

s=os.system('powershell Write-Host "I am so bored with this. Work already" -ForegroundColor Blue')

否则:

←[94mPff

另一种选择是使用NodeJS。

这里有一个例子:

const os = require('os');
const colors = require('colors');

console.log("Operative System:".green,os.type(),os.release());
console.log("Uptime:".blue,os.uptime());

这就是结果:

I'm adding an answer to address an issue noted in some comments above: that inline ansi color codes can misbehave when inside a FOR loop (actually, within any parenthesized block of code). The .bat code below demonstrates (1) the use of inline color codes, (2) the color failure that can occur when inline color codes are used in a FOR loop or within a parenthesized block of code, and (3) a solution to the problem. When the .bat code executes, tests 2 and 3 demonstrate the colorcode failure, and test 4 shows no failure because it implements the solution.

[编辑2020-04-07:我发现了另一个解决方案，可能比调用子例程更有效。将FINDSTR短语括在括号中，如下所示:

   echo success | (findstr /R success)

ENDEDIT]

注意:根据我的(有限的)经验，颜色代码问题只有在输入被管道输送到代码块中的FINDSTR之后才会出现。这就是下面的.bat重现问题的方式。颜色代码问题可能比输送到FINDSTR之后更普遍。如果有人能解释问题的本质，如果有更好的解决方法，我会很感激。

@goto :main
:resetANSI
EXIT /B
rem  The resetANSI subroutine is used to fix the colorcode
rem  bug, even though it appears to do nothing.

:main
@echo off
setlocal EnableDelayedExpansion

rem  Define some useful colorcode vars:
for /F "delims=#" %%E in ('"prompt #$E# & for %%E in (1) do rem"') do set "ESCchar=%%E"
set "green=%ESCchar%[92m"
set "yellow=%ESCchar%[93m"
set "magenta=%ESCchar%[95m"
set "cyan=%ESCchar%[96m"
set "white=%ESCchar%[97m"
set "black=%ESCchar%[30m"

echo %white%Test 1 is NOT in a FOR loop nor within parentheses, and color works right.
   echo %yellow%[Test 1] %green%This is Green, %magenta%this is Magenta, and %yellow%this is Yellow.
   echo %Next, the string 'success' will be piped to FINDSTR...
   echo success | findstr /R success
   echo %magenta%This is magenta and FINDSTR found and displayed 'success'.%yellow%
   echo %green%This is green.
echo %cyan%Test 1 completed.

echo %white%Test 2 is within parentheses, and color stops working after the pipe to FINDSTR.
(  echo %yellow%[Test 2] %green%This is Green, %magenta%this is Magenta, and %yellow%this is Yellow.
   echo %Next, the string 'success' will be piped to FINDSTR...
   echo success | findstr /R success
   echo %magenta%This is supposed to be magenta and FINDSTR found and displayed 'success'.
   echo %green%This is supposed to be green.
)
echo %cyan%Test 2 completed.

echo %white%Test 3 is within a FOR loop, and color stops working after the pipe to FINDSTR.
for /L %%G in (3,1,3) do (
   echo %yellow%[Test %%G] %green%This is Green, %magenta%this is Magenta, and %yellow%this is Yellow.
   echo %Next, the string 'success' will be piped to FINDSTR...
   echo success | findstr /R success
   echo %magenta%This is supposed to be magenta and FINDSTR found and displayed 'success'.
   echo %green%This is supposed to be green.
)
echo %cyan%Test 3 completed.

echo %white%Test 4 is in a FOR loop but color works right because subroutine :resetANSI is 
echo called after the pipe to FINDSTR, before the next color code is used.
for /L %%G in (4,1,4) do (
   echo %yellow%[Test %%G] %green%This is Green, %magenta%this is Magenta, and %yellow%this is Yellow.
   echo %Next, the string 'success' will be piped to FINDSTR...
   echo success | findstr /R success
   call :resetANSI
   echo %magenta%This is magenta and FINDSTR found and displayed 'success'.
   echo %green%This is green.
)
echo %cyan%Test 4 completed.%white%

EXIT /B
