PowerShell v5中的注解着色可以通过Set-PSReadlineOption修改。以下命令将注解的前景和背景颜色设置为shell前景和背景颜色：

Set-PSReadlineOption -TokenKind Comment -ForegroundColor $Host.UI.RawUI.ForegroundColor -BackgroundColor $Host.UI.RawUI.BackgroundColor

字符串
或者只有黑色和白色：

Set-PSReadlineOption -TokenKind Comment -ForegroundColor Black -BackgroundColor White

型
您需要对所有TokenKind值执行此操作，以完全删除语法着色。
如果你还想改变输出流的颜色，你可以通过主机的PrivateData对象的属性来实现：

$Host.PrivateData.WarningForegroundColor = $Host.UI.RawUI.ForegroundColor
$Host.PrivateData.WarningBackgroundColor = $Host.UI.RawUI.BackgroundColor
...

型
将所有这些语句放入profile中，以便在每次启动PowerShell时应用它们，例如：

$HOME\Documents\WindowsPowerShell\profile.ps1

型

语法在最近的一次更新中发生了变化。旧的语法现在会给你给予一个讨厌的错误消息：

Set-PSReadLineOption : A positional parameter cannot be found that accepts argument 'Command'.

更新后的语法似乎要求您传入新设置的字典。

Set-PSReadLineOption -Colors @{None='black';Comment='black';Keyword='black';String='black';Operator='black';Variable='black';Command='black';Parameter='black';Type='black';Number='black';Member='black'}

型
如果你得到

Set-PSReadLineOption: 'None' is not a valid color property

型
取出None='black';，像这样：

Set-PSReadLineOption -Colors @{Comment='black';Keyword='black';String='black';Operator='black';Variable='black';Command='black';Parameter='black';Type='black';Number='black';Member='black'}

以下是我在OSX中如何处理那些立即困扰我的事情：

$a = get-psreadlineoption | select ErrorBackgroundColor
$clear = $a.ErrorBackgroundColor

'command','number','operator','member' |
foreach { set-psreadlineoption $_ black $clear }
