How to concatenate 2 Write-Output on the same line? - powershell

Question

I wrote a script that can return you if a software is installed or not.
I would like to give it a bit of colors but I don't know how to concatenate 2 Write-Output on the same line as -NoNewline only works for Write-Host... which in this case I cannot use:
# The function we use to give color
function Positive {
process { Write-Host $_ -ForegroundColor Green }
}
function Negative {
process { Write-Host $_ -ForegroundColor Red }
}
# Is the software installed?
# '0' = NO, is not installed
# '1' = YES, is installed
$Check = '1'
function Check_Installation($Check){
if ($Check -eq '0') {return $response = "No, is not installed" | Negative}
elseif ($Check -eq '1') {return $response = "Yes, is installed" | Positive}
}
$First_Phrase = "Let's check if the software is installed: "
Write-Output "$First_Phrase", "$response"
Check_Installation($Check)
I know I can concatenate with
[string]::Concat("$First_Phrase", "$response")
but is not working.

This works in console only as changing the foreground colour in ISE changes it for every line:
# The function we use to give color
function Set-Output {
param ($colour, $str1, $str2)
$t = $host.ui.RawUI.ForegroundColor
$host.ui.RawUI.ForegroundColor = "$colour"
$text = "$str1 $str2"
Write-Output "$text"
$host.ui.RawUI.ForegroundColor = $t
}
# Is the software installed?
# '0' = NO, is not installed
# '1' = YES, is installed
$Check = '1'
$First_Phrase = "Let's check if the software is installed: "
Switch ($check) {
( 0 ) {Set-Output -colour RED -str1 $First_Phrase -str2 "No, is not installed" }
( 1 ) {Set-Output -colour GREEN -str1 $First_Phrase -str2 "Yes, is installed" }
}
Check_Installation($Check)
All that it is doing is concatenating the two strings and changing the foreground colour.
