Transparent PNG with color fill overlay

[DeNitE_Appz]

How can I make a transparent PNG and colorize it with a color fill on it? I was able to figure it out with a greyscale 8bit image with a black background, but can't get it working with a transparent background. I've seen it done when I decompiled a sample face, so I know it's possible. I'm assuming it's the way the image is saved that makes the difference...

How about having a separate view to display a solid background?

//this is the background

<view id="background">

//the transparent image goes here

<image>...
