Answer 1

Here is small a function I wrote to output colored text (it is actually smaller, but I rewrote it to be more understandable):

function Write-Color() {
    Param (
        [string] $text = $(Write-Error "You must specify some text"),
        [switch] $NoNewLine = $false
    )

    $startColor = $host.UI.RawUI.ForegroundColor;

    $text.Split( [char]"{", [char]"}" ) | ForEach-Object { $i = 0; } {
        if ($i % 2 -eq 0) {
            Write-Host $_ -NoNewline;
        } else {
            if ($_ -in [enum]::GetNames("ConsoleColor")) {
                $host.UI.RawUI.ForegroundColor = ($_ -as [System.ConsoleColor]);
            }
        }

        $i++;
    }

    if (!$NoNewLine) {
        Write-Host;
    }
    $host.UI.RawUI.ForegroundColor = $startColor;
}

It's quite simple to use: just use Write-Color "your text" and add some color name between curly brackets where you want the text to be colored.

Examples:

`Write-Color "Hello, {red}my dear {green}friend !"` will output

You can put it in your $profile file to use it in a simple PowerShell prompt, or just add it to some scripts.
