Powershell Integrated Console colors wrong

[ChristopherGLewis]

The Powershell IC doesn't display certain background and foreground colors the same as the ISE and CMD.Exe shell.

Main issue is a Background color of BLACK shows up as white, GRAY shows up as dark gray, DARK GRAY shows up as gray, and WHITE shows up as a third gray.

Also, when foreground and background are the same color, the IC defaults to white on white.

Simple script to test

$FGcolors = [enum]::GetValues([System.ConsoleColor])
$BGcolors = [enum]::GetValues([System.ConsoleColor])
$size = 10 

Write-Host "".PadRight($Size).Substring(0,$size) -NoNewline
Foreach ($BGcolor in $BGcolors) {
    Write-Host $BGcolor.ToString().PadRight($Size).Substring(0,$size)  -BackgroundColor $BGcolor -NoNewline
}
Write-Host 
Foreach ($FGcolor in $FGcolors) {
    Write-Host  $FGColor.ToString().PadRight($Size).Substring(0,$size) -foreground $FGColor -NoNewline

    Foreach ($BGcolor in $BGcolors)
    {
         Write-Host   $FGColor.ToString().PadRight($Size).Substring(0,$size) -background $BGColor -foreground $FGColor -nonewline
    }
    Write-Host 
}

Thanks for the repro script Chris! Seems like this may be an issue with VS Code's terminal implementation, I get the same results both in the PowerShell Integrated Console and the normal integrated terminal running powershell.exe.

Here's what it looks like for me from within powershell.exe (ignore the exact colors, I'm using a theme):

Hey @Tyriar, do you have any ideas on what might be going on with the terminal colors here?

[Tyriar]

So winpty will transform the powershell colors to xterm escape sequences that are read and displayed by xterm.js. AFAIK there is no issue with the xterm.js logic so maybe there is a problem with winpty translating these?

I don't know if this is a related issue, but I'm having some trouble with colors too...

It may be a problem with Pshazz (it works fine on powershell, though).

@NemoStein I think this normally happens when you tweak the default colors of cmd.exe
