小林博客Windows 批处理脚本中打印彩色内容，通常的方式是 echo [32mHello World[0m，但这种方式需要输入特殊字符 ESC（ASCII 码为 27），我试过 Alt+027 的快捷键却怎么也打不出来这个字符，而且这种方式各个颜色的编码也很不好记，分享一种更简单的方法！

powershell -Command "Write-Host 'This is Black' -ForegroundColor White -BackgroundColor Black"
powershell -Command "Write-Host 'This is DarkBlue' -ForegroundColor White -BackgroundColor DarkBlue"
powershell -Command "Write-Host 'This is DarkGreen' -ForegroundColor White -BackgroundColor DarkGreen"
powershell -Command "Write-Host 'This is DarkCyan' -ForegroundColor White -BackgroundColor DarkCyan"
powershell -Command "Write-Host 'This is DarkRed' -ForegroundColor White -BackgroundColor DarkRed"
powershell -Command "Write-Host 'This is DarkMagenta' -ForegroundColor White -BackgroundColor DarkMagenta"
powershell -Command "Write-Host 'This is DarkYellow' -ForegroundColor White -BackgroundColor DarkYellow"
powershell -Command "Write-Host 'This is Gray' -ForegroundColor Black -BackgroundColor Gray"
powershell -Command "Write-Host 'This is DarkGray' -ForegroundColor White -BackgroundColor DarkGray"
powershell -Command "Write-Host 'This is Blue' -ForegroundColor White -BackgroundColor Blue"
powershell -Command "Write-Host 'This is Green' -ForegroundColor White -BackgroundColor Green"
powershell -Command "Write-Host 'This is Cyan' -ForegroundColor Black -BackgroundColor Cyan"
powershell -Command "Write-Host 'This is Red' -ForegroundColor White -BackgroundColor Red"
powershell -Command "Write-Host 'This is Magenta' -ForegroundColor White -BackgroundColor Magenta"
powershell -Command "Write-Host 'This is Yellow' -ForegroundColor Black -BackgroundColor Yellow"
powershell -Command "Write-Host 'This is White' -ForegroundColor Black -BackgroundColor White"
其中单引号内是打印的文字内容，ForegroundColor 参数传文字颜色，BackgroundColor 参数传背景颜色，直接传颜色名字，非常方便。
如果在批处理中使用，可以定义一个函数，调用起来更简洁。
@echo off
call :print "Hello, world!" Yellow Red
call :print "Hello, iMaeGoo!" White Blue
exit /b 0
:print
powershell -Command "Write-Host '%1' -ForegroundColor %2 -BackgroundColor %3"
goto:eof
效果、
