I have a couple of scripts written in powershell which are opening a window and showing some text. I would like for every of this windows to have a different background color. At the same time I would like to format the text, which is shown on every window, based on different regexps.
For instance I have 2 windows:

First Window

1. I want the background to be gray
2. I want the phrase 2024 to be in different color
3. I want the phrase eee to be in different color

Second window:

1. I want the background to be white
2. I want the phrase 2024 to be in different color
3. I want the phrase eee to be in different color

I have created a script which suppose to facilitate that but the effect is not correct:

.

Although the background was set to gray, when I start to “colour” the phrases the output is losing the initial background color.

The script is as follows:

function Set-ConsoleColor ($bc, $fc) {
    $Host.UI.RawUI.BackgroundColor = $bc
    $Host.UI.RawUI.ForegroundColor = $fc
    Clear-Host
}
Set-ConsoleColor 'gray' 'white'
$green = [char]27 + "[32m"
$blue = [char]27 + "[34m"
$reset = [char]27 + "[0m"
$content ="2024 bbb ccc ddd eee fff"
$coloredLine = $content  -replace "eee", "$green`$&$reset"  -replace "2024", "$blue`$&$reset"

Write-Output $coloredLine
Start-Sleep -Seconds 10

How can I achieve effect like in the first or second image?
