Help with Transparency layering

rich404
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.

Just a suggestion, probably more work than you are planning on.

Use layermasks, one for each major colour. Black layer mask and paint in it in
white - this is your selection.

Paint in the associated layer to add details. The great thing about layer masks
is they are non destructive, go back and adjust any time you like.

quick example shown and gimp xcfgz attached.

Alternatives.

Any selection can be saved as a channel to be called back at a later date.

The Gimp plug-in g'mic www.gmic.eu has an excellant filters to colorize
grayscale photographs. That does the hard work using color swatches, leaving
touch-up to you.

Thank you, but I figured out a way based on the more simple needs I have. By
copying and Merging layers I am able to systematically remove the parts I don't
want to paint over. Thank you for your help though.
