Powershell: Trying to change back/foreground colors to text output (no Write-Host)

As the title suggests, I'm trying to change color of the fore/background of text outputed by: {$_.Name +" Drive: Used: "+"{0:N2}" -f($_.Used/1gb) + " Free: "+"{0:N2}" -f($_.Free/1gb) + " Total: "+"{0:N2}" -f(($_.used/1gb) + ($_.Free/1gb));

Where Drive, Used, Free, Total text output is I would like to add some foreground and background, but I cannot figure out how can I do that.

I'm trying to poke the script from internet in order to learn some new things with Powershell.

Full script: Get-PSDrive | Where-Object{$_.Free -gt 1} | ForEach-Object{$count = 0 ; "`n" }{$_.Name + " Drive: Used: " +"{0:N2}" -f($_.Used/1gb) + " Free: "+"{0:N2}" -f($_.Free/1gb) + " Total: "+"{0:N2}" -f(($_.used/1gb) + ($_.Free/1gb)); $count = $count + $_.Free;}{Write-Host "Total Free Space: " ("{0:N2}" -f($count/1gb)) -ForegroundColor White -BackgroundColor Black}

For PowerShell 7.2 you can easily use the automatic variable $PSStyle:

$FG_LIGHT_BLUE = $PSStyle.Foreground.FromRgb(0x0099ff)
$Message = "Light blue text"
Write-Host "`r$FG_LIGHT_BLUE$Message$($PSStyle.Reset)"

One can do color without Write-host by using...

PSHostUserInterface.RawUI Property

$host.UI.RawUI.ForegroundColor = 'YourColorChoice'
$host.UI.RawUI.BackgroundColor = 'YourColorChoice'

... in all PowerShell versions. See this article.

Or using the .Net namespace...

[console]::ForegroundColor = 'YourColorChoice'
[console]::BackgroundColor = 'YourColorChoice'

... in all PowerShell versions. See this article.

You've already been pointed to the Ansi/VT stuff in PowerShell v5x.

either write your own functions to use those or know that there are several modules available to address this use case.

Find-Module -Name '*color*' | Format-Table -AutoSize

PSWriteColor is the one I'd recommend. See this article about it. Though it is really a wrapper module.

Windows 10 + PowerShell 5.1 and later supports ANSI escape sequences by default.

ANSI escape code #DOS and Windows - Wikipedia

and you need to use a special character for [esc] in PowerShell.

# PowerShell version 5
"$([char]0x1b)[30;41m YOUR_TEXT_HERE $([char]0x1b)[0m"

# PowerShell version 6+
"`e[30;41m YOUR_TEXT_HERE `e[0m"
