The information provided here by Chosen and Robin has been so helpful in understanding the alpha process! Thanks!
My question is - how do you apply color to a alpha transparency? I've used shades of gray to create frost and other stuff on windows but wonder how you achieve the lovely effects of stained glass and silkscreen-like patterns on translucent/transparent textures.
Thanks, again, for all your help!

Thanks, again, for all your help! I (believe) you would paint it as normal, as if it is not transparent, then do a partial alpha over the colour, though I'm not certain, not having yet done it.

Yes, that's just right. The alpha channel controls transparency and your RGB channels control the hue. If you have a semi-transparent area, the alpha shows gray in those areas rather than either white or black. That's independent of whatever your RGB channels show in those areas. So if you are making, say, red lace, you color it the way you usually do. The only thing that is different is the alpha channel.

Eureka! I think I've figured it out!

I'm in PaintShopPro11 - paste my stained glass image as a new layer, make a new mask layer, and paint on the mask layer with whatever shade of gray to achieve transparency. Then, of course, save to an alpha channel and finally save a copy as .tga. As with other alphas, the darker the gray, the more transparent the image.
