[Gimp-user] Help with Transparency layering

[ZevVeli <forums gimpusers com>]

Okay, not sure if this is the right forum for this, but I'm trying to do some
coloring on a greyscale image. Now, I know how to apply a transparency, and
select down so that the new layer is only taking the opaque area that I am
working with, but I'm trying to figure out how to eliminate the selection I've
colored in from further layers. Or in other words: I have colored in say, the
skin, of my image, now I want to create a new layer keeping my prior
transparencies but without the skin that I have already covered, that way I
don't accidentally color over the skin while applying color to the figure's hair
or clothing.
