line art layer selection
I'd like to draw a line art in a layer and than create a second layer for coloring it, so i don't have to go around cleaning up white dots near my lines inbetween for exapmle my brown color. So now is there a way to select the space inbetween shapes i make in one layer and color them in, in a second one?
It's easy enough to just manually color around the edges, in the second layer, when the lines are thick enough so i don't have to nervously spend time making sure colors aren't overlapping, but this is quite impractical when doing 1 pixel broad lines.

RE: line art layer selection
Assuming your lines create "closed" areas
1) make a fuzzy select of the area you want to paint
2) select/grow the selection by one pixel
3) bucket-fill the same layer after setting the bucket-fill to "behind" mode ("behind" mode is available for all paint tools).
4) You can also bucket-ill (in "normal" mode) in a separate layer under the line drawing.

The result with "behind" paint mode on same layer:


(using "normal" mode on a separate layer gives identical results).

The "line art" was emulated by stroking a path with a 1-pixel line, see attached XCF.

See here for some more information.

(*) If they don't:
- duplicate the drawing layer, and add extra lines to close them
- perform the selection above using that layer
- switch to the original layer for the bucket fill.
