Cannot change console colors

I have tried to use these to customise my PowerShell console, but they all seem broken. The BackgroundColor goes black, but as soon as I type something like dir everything is in the default blue background again. I've been doing quite a few web searches and cannot find a way to just change this. Do you know a way to change the console so that I can make the BackgroundColor hold?

$Shell = $Host.UI.RawUI
$Shell.BackgroundColor = "Black"
$Shell.ForegroundColor = "White"
$Shell.CursorSize = 10

This page suggests adding these values to $profile to make them stick in the console session, but this does not work. https://4sysops.com/wiki/change-powershell-console-syntax-highlighting-colors-of-psreadline/

Is there some other PSReadLine function (possibly a PS v5.1 option) that does allow permanently fixing the console colors in a session?

* Set-PSReadLineOption options have changed
  - To specify colors, use the new `-Color` parameter and pass a Hashtable

No example on how to change backgroundcolor though...

Someone once said:

PowerShell 5.0 on Windows 10 ships with a much-enhanced and colorful PowerShell console. PowerShell 5.0 on other operating systems just has the dull standard console.

That's because the console enhancements come from a module called "PSReadLine". If you installed PowerShellGet (which is always part of PowerShell 5.0 and can be downloaded from www.powershellgallery.com for older PowerShell versions), you can download this module and turn your console into a colorful beast as well:

# download and install the module
Install-Module PSReadLine -Scope CurrentUser

# load the module to turn on the colors
# this could be done automatically in your $profile script
Import-Module PSReadline

However, PSReadline is now in PowerShell distributions by default, no download needed. SO, there is a matter of precedence based on the config you choose. You can disable PSReadline, to validate if it is truly PSReadline as your root case or the default of PowerShell.
