I think this would be better:

because if ect. the red-component is
under DARKEN_VALUE it will... eh... fuck-up :)
(This also looks better)

DARKEN_VALUE = 0.5 // Or whatever

foreach([x, y] of pixel_in_shadow_region)
{
   pix = GetPixelOfUnderlyingRegion(x, y);

   red = GetRedComponent(pix);
   green = GetGreenComponent(pix);
   blue = GetBlueComponent(pix);

   red = red * DARKEN_VALUE;
   green = green * DARKEN_VALUE;
   blue = blue * DARKEN_VALUE;

   pix = RGB(red, green, blue);

   SetPixelOfUnderlyingRegion(pix, x, y);
}
