Powershell ISE, HEX colors - Me make pretty!

This is just a way to add more color to the output in ISE.
Note that: There is no '-NoNewLine' available - 'PrivateData.' Does not include it.

# Note that in that '#AABBCCDD' pattern used below -
    # The 'AA' portion is the 'transparency' (followed by the HEX color value 'BBCCDD') - So;
        # FF, is the HEX equvalent of 255, full value, NO 'transparency' - Full color.
        # 80, in HEX, is equal to 128 (about half of 255), so would be about 50% 'transparency'
        # 00, in HEX, is 00 (zero), so would be completley transparent - No color.

# If that 'AA' portion is omitted, and just the #Hex value is used, it still works just fine.
    ## So, For example, on that '$host.PrivateData.ErrorBackgroundColor' line -
    ### '#7B00FF' and '#FF7B00FF' - Mean the same thing. NO 'transparency' - Full color.
If (($host.Name) -match "ISE") {
    # This just gathers the current / default Error reporting colors, so they can be restored.
    $ErrFgCol = (((((($host.privatedata) | Out-String).Split("`n|`r",[System.StringSplitOptions]::RemoveEmptyEntries))[13]).Split(':'))[1]).Trim()
    $ErrBgCol = (((((($host.privatedata) | Out-String).Split("`n|`r",[System.StringSplitOptions]::RemoveEmptyEntries))[14]).Split(':'))[1]).Trim()
        $host.PrivateData.ErrorForegroundColor  = '#FFFF8C00' # Set the color to Orange, for example.
        $host.PrivateData.ErrorBackgroundColor  = '#FF7B00FF' # Set the color to Purple, for example
            $host.UI.WriteErrorLine('         WORDS         ')
        $host.PrivateData.ErrorForegroundColor  = $ErrFgCol # Set the color back to its default - Red / '#FFFF0000'
        $host.PrivateData.ErrorBackgroundColor  = $ErrBgCol # Set the color back to its default - Red / '#00FFFFFF'
} Else {
Write-Host " This will only work in Powershell ISE." -ForegroundColor Yellow -BackgroundColor DarkRed
Write-Host "  Any key, to continue..." -NoNewline -ForegroundColor Green -BackgroundColor DarkCyan

# List all Hex values 0 - 255
0..255 | % {Write-Host "$_`: $((('{0:x2}' -f $_).ToString()).ToUpper())"}
