Changing Verbose colors in PowerShell 7.2

I expected the following code to print verbose text with my default foreground color:

$Host.PrivateData.VerboseForegroundColor = [console]::ForegroundColor
Write-Verbose 'Test' -Verbose

However, it prints yellow text as usual. Changing the Error foreground color does work though:

$Host.PrivateData.ErrorForegroundColor = [console]::ForegroundColor
Write-Error 'test'

The only way I've found to circumvent this is by doing this:

Write-Verbose 'Test' -Verbose *>&1 | Write-Host

But this isn't really changing the verbose colors, it's just forcing it to print directly to the console host as default text using Write-Host. I do know that Write-Host does let you alter the message color to anything you want, but this is hardly an ideal solution.

In Powershell 7.2+, $Host.PrivateData not the right way to set styles. It's there for backwards compatibility. For details, see a brand new about_* page: about_ANSI_Terminals

You want

enter image description here

$PSStyle.Formatting.Verbose = $PSStyle.Foreground.FromRgb(0x34f2aa)

Check out the docs, it adds a bunch of options: bold, blink, hidden, reverse, italic, underline, fileinfo.... about_ANSI_Terminals

Test it out

function testVerbose { 
   [CmdletBinding()]
   param( [Parameter() ]$x )
   "$x"
   $X.GetType().FullName | write-verbose
   
}

testVerbose 34.5 -Verbose                                             ; 

$PSStyle.Formatting.Verbose = $PSStyle.Foreground.FromRgb(0x34f2aa)

testVerbose 34.5 -Verbose

Viewing ansi escapes

One way to view the ANSI control chars is to replace "``e".

# I saved the value before changing it
$originalVerbose -replace "`e", ''

$PSStyle.Formatting.Verbose -replace "`e", ''

enter image description here

Notice: It switched to the 24bit-color ANSI escape sequence

Printing all control chars

Format-ControlChar converts all control chars to their Symbol version, not just e, making values safe to pipe.

It's easy, just add 0x2400 to the codepoint. compart.com/block/U+2400

> "$($PSStyle.Background.BrightCyan)Power$($PSStyle.Underline)$($PSStyle.Bold)Shell$($PSStyle.Reset)"
    | Format-ControlChar
