Just a note to anyone reading this. It is important to give all information. If your forum profile says gimp 2.8 expect replies based on Gimp 2.8
Gimp 2.10 has evolved and the latest version does have some extra features than earlier versions. Please give the whole version number. Easy to determine, the Gimp menu Help -> About will tell you.
Quote:I need to work with an imported line drawing of shingles and I want to color them with various shades of gray. The image I used is fine except that it imports with some black lines and some gray, even though it is black-and-white.
Always difficult to give advice with a jpeg screenshot of what must be a larger image. I can see that there is some transparency there but it is not black and white. Black is not black (percentages not zero) and the line is a grey. With an image like that, fuzzy select / colour select even with zero threshold only gives a partial selection. A colour erase brush takes out part of the line as well, as does color-to-alpha.
If you want to paint in various shades of grey, keeping the 'lines' then you need just the lines on transparency and just-my-opinion, the easiest way is re-create on a new layer painting in the lines. Then colour under that. Of course you can always go in at a pixel level on a single layer and paint each area individually.
Whatever happened to making a tiles pattern? as https://www.gimp-forum.net/Thread-Roof-tiles
Here is a part of the original line drawing png that needs to be colored in shades of grays. The lines need to be darkened and made more solid.
