  intGammaRed = (intRed - 128) * 32
  intGammaGreen = (intGreen - 128) * 32
  intGammaBlue = (intBlue - 128) * 32
  
  intRed   = Int((intGammaRed / 32) + 128)
  intGreen = Int((intGammaGreen / 32) + 128)
  intBlue  = Int((intGammaBlue / 32) + 128)```

• https://pawelporwisz.pl/winamp/ColorThemes/wct_en.php The 'gammagroup' object is an element that defines specific GUI element (for example: Titlebar). It contains 'id', 'value', 'gray' and 'boost' attributes.

  The id attribute declares the name of GUI element that we want to describe The value attribute declares the color of specific GUI element (in RGB or HSL scale, scope is -4096 to 4096) The gray attribute defines grayscale value (1 or 2). When set to "1" the gammagroup elements will be treated as having a light gray base. When set to "2" the gammagroup elements will be treated as having a dark gray base. The boost attribute defines saturation (0 or 1). When set to "1", boost brightens up the gammagroup by adding 50% more white to it.
