I've been experimenting with coloring a line drawing. A made a quick sample shingle roof, imported it as a TIF into Gimp. The lines were pretty gray so I needed them darker. Erode didn't give me the results I wanted so, I used Select By Color and darkened the lines. I wanted to color in the tiles individually so I took a small sample, colored it all a darker gray color with the intention of returning to make a few of the shingles a lighter value. But adding the color had the effect of "erasing" the lines defining the individual shingles so when I tried to color a single tile the lighter color the whole thing turned the lighter color.
How can I set this up to keep the line art and color individual shingles?
