My PowerShell, Posh-Git and .gitconfig color configuration because of some red-green troubles with the default configurations.

in the land of the blind, the one-eyed man is king

PowerShell

List current colors

function Show-Colors() {
  Write-Host "Available Colors:"
  $colors = [Enum]::GetValues([ConsoleColor])
  $max = ($colors | foreach { "$_ ".Length } | Measure-Object -Maximum).Maximum
  foreach ($color in $colors) {
    Write-Host (" {0,2} {1,$max} " -f [int]$color,$color) -NoNewline
    Write-Host "$color" -Foreground $color
  }

  Write-Host ""
  Write-Host "Current Configuration:"
  $host.PrivateData |
    Get-Member -MemberType Property |
    Select-Object Name,@{label='Value';exp={$host.PrivateData.($_.Name)}} |
    Format-Table -AutoSize

  Write-Host ""
  Write-Host "Current Configuration (visualized):"
  $colors = $host.PrivateData
  Write-Host Error -Back $colors.ErrorBackgroundColor -Fore $colors.ErrorForegroundColor
  Write-Host Warning -Back $colors.WarningBackgroundColor -Fore $colors.WarningForegroundColor
  Write-Host Debug -Back $colors.DebugBackgroundColor -Fore $colors.DebugForegroundColor
  Write-Host Verbose -Back $colors.VerboseBackgroundColor -Fore $colors.VerboseForegroundColor
  Write-Host Progress -Back $colors.ProgressBackgroundColor -Fore $colors.ProgressForegroundColor
}
Show-Colors

With just changing how Errors are displayed, everything is readable, for me, with Cmder.

$host.PrivateData.ErrorBackgroundColor = 'Red'
$host.PrivateData.ErrorForegroundColor = 'Yellow' # or: "DarkMagenta"

Posh-Git

List current configuration

$GitPromptSettings

v0.x

My changes

$global:GitPromptSettings.WorkingForegroundColor = [ConsoleColor]::Yellow
$global:GitPromptSettings.BranchForegroundColor = [ConsoleColor]::Green

Get possible colors

[ConsoleColor].GetEnumNames()

• Gray, Blue, Green, Cyan, Red, Magenta, Yellow, White
• Black, DarkBlue, DarkGreen, DarkCyan, DarkRed, DarkMagenta, DarkYellow, DarkGray

v1.x

Some breaking changes…

$GitPromptSettings.DefaultPromptPath.ForegroundColor = 'White'

$GitPromptSettings.LocalWorkingStatusSymbol.ForegroundColor = 'Yellow'
$GitPromptSettings.WorkingColor.ForegroundColor = 'Yellow'

$GitPromptSettings.BranchAheadStatusSymbol.ForegroundColor = 'Green'
$GitPromptSettings.BranchBehindStatusSymbol.ForegroundColor = 'DarkMagenta'
$GitPromptSettings.BranchBehindAndAheadStatusSymbol.ForegroundColor = 'Yellow'

Colors are interpreted with

System.Drawing.ColorTranslator.FromHtml()

Git

List current colors

git config --list | Where-Object {$_ -Like "color*"}

~/.gitconfig

Available colors: normal, black, red, green, yellow, blue, magenta, cyan, or white
Second optional color param values: bold, dim, ul (underline), blink, and reverse (swap foreground and background)

[color "branch"]
	current = yellow
	local = white
	remote = magenta

[color "status"]
	header = white
	changed = magenta bold
	untracked = magenta bold
	unmerged = magenta reverse
	added = yellow
	branch = white

[color "diff"]
	meta = blue white
	frag = normal bold
