Host.ui.rawui.foregroundcolor/backgroundcolor are not set on mac

[plastikfan]

this causes errors when trying to write in colour.

The following code in Krayon constructor cause error, because for some reason it is set to -1:

    $this._defaultFgc = (Get-Host).ui.rawui.ForegroundColor;
    $this._defaultBgc = (Get-Host).ui.rawui.BackgroundColor;

This appears to be a problem in PowerShell.

On mac:

λ $host.ui.RawUI.ForegroundColor
-1


λ (get-host).ui.rawui | Format-List -Property *

ForegroundColor       : -1
BackgroundColor       : -1
CursorPosition        : 0,52
WindowPosition        : 0,0
CursorSize            : 100
BufferSize            : 214,53
WindowSize            : 214,53
MaxWindowSize         : 214,53
MaxPhysicalWindowSize : 214,53
KeyAvailable          : False
WindowTitle           :

On windows:

λ (get-host).ui.rawui | Format-List -Property *

ForegroundColor       : Gray
BackgroundColor       : Black
CursorPosition        : 0,59
WindowPosition        : 0,0
CursorSize            : 25
BufferSize            : 213,60
WindowSize            : 213,60
MaxWindowSize         : 213,60
MaxPhysicalWindowSize : 1904,70
KeyAvailable          : True
WindowTitle           : Elizium.Krayola

This is being tracked under PowerShell issue: ui.RawUI on result of 'Get-Host' contains ForegroundColor/BackgroundColor set to -1 on macOS

Leaving this issue open purely to track the underlying issue.
