function Set-ISEColorAdjustment { <# .SYNOPSIS Applies a tone adjustment to an ISE color theme object. .DESCRIPTION The Set-ISEColorAdjustment function processes theme color data and shifts the RGB values based on the specified adjustment type—Cooler, Warmer, Greener, Darker, or Lighter. The function returns a new array of color objects with updated ARGB and hexadecimal values. Font-related metadata (the "Other" class) is preserved but not modified. .PARAMETER ThemeData An array of color theme objects, typically retrieved from Get-ISETheme or Get-CurrentISETheme. .PARAMETER Adjustment The type of tonal shift to apply to the color set. Options include: Cooler, Warmer, Greener, Darker, Lighter. .PARAMETER Degree Controls the intensity of the adjustment (default is 20). Higher values amplify the color shift. .EXAMPLE $adjusted = Set-ISEColorAdjustment -ThemeData $theme -Adjustment 'Cooler' Applies a cooler color bias to the theme data and returns the adjusted set. .EXAMPLE $adjusted = Set-ISEColorAdjustment -ThemeData $theme -Adjustment 'Darker' -Degree 40 Darkens the entire theme by 40 units and returns the modified objects. .NOTES Author: Jeff Pollock GitHub: https://github.com/phriendx/ISEColorTheme.cmdlets Website: https://pxlabs.info #> [CmdletBinding()] param ( [Parameter(Mandatory)] [array]$ThemeData, [Parameter(Mandatory)] [ValidateSet("Cooler", "Warmer", "Greener", "Darker", "Lighter")] [string]$Adjustment, [int]$Degree = 20 ) $Subtract = $Degree / 2 $AdjustedColors = @() foreach ($Attribute in $ThemeData) { if ($Attribute.Class -eq 'Other') { continue } $var_A = $Attribute.A $var_R = $Attribute.R $var_G = $Attribute.G $var_B = $Attribute.B switch ($Adjustment) { "Cooler" { $var_R = [math]::Max(0, $var_R - $Subtract) $var_B = [math]::Min(255, $var_B + $Degree) } "Warmer" { $var_R = [math]::Min(255, $var_R + $Degree) $var_B = [math]::Max(0, $var_B - $Subtract) } "Greener" { $var_R = [math]::Max(0, $var_R - ($Subtract / 2)) $var_G = [math]::Min(255, $var_G + $Degree) $var_B = [math]::Max(0, $var_B - ($Subtract / 2)) } "Darker" { $var_R = [math]::Max(0, $var_R - $Degree) $var_G = [math]::Max(0, $var_G - $Degree) $var_B = [math]::Max(0, $var_B - $Degree) } "Lighter" { $var_R = [math]::Min(255, $var_R + $Degree) $var_G = [math]::Min(255, $var_G + $Degree) $var_B = [math]::Min(255, $var_B + $Degree) } } $Hex = Convert-ARGBToHex "$var_A,$var_R,$var_G,$var_B" $colorObj = [PSCustomObject]@{ Class = $Attribute.Class Attribute = $Attribute.Attribute A = $var_A R = $var_R G = $var_G B = $var_B Hex = $Hex } $AdjustedColors += $colorObj } return $AdjustedColors } |
