I'm importing a mass of .bmps with icon.Shift(), and to make the background transparent I'm SwapColor()ing to change it to a transparent color, yet no avail as of yet.

I've attempted swapping it with rgb(192,192,192) (#C0C0C0), yet the background of the icon isn't transparent in the .dmi. I've also tried 172,172,172 (courtesy of Audeuro), yet the background of the icon isn't transparent.

What's the correct transparent background color?
SwapColor(rgb(192,192,192), null)

I think that's what you're talking about.
