I know I can change PowerShell console colors by setting in my profile something like:
$Host.UI.RawUI.BackgroundColor = \"White\" Clear-Host
The correct way to do this is with the Registry
cd hkcu:/console $0 = '%systemroot%_system32_windowspowershell_v1.0_powershell.exe' ni $0 -f sp $0 ColorTable00 0x00562401 sp $0 ColorTable07 0x00f0edee
With the color being
0x00BBGGRR
