How to create an overspray effect?

I tried fading out the selection and fill it with one color on a background layer and tried different brushes and tools, but without luck. It's mainly to geht the spray painted look at all.



no overspray



Edit to clean up the question

  • Why not simply use a scatter like brush to paint with red over the edges or apply it to a path along the edge or another x ways :)

You can ask GIMP questions here. Here's a super easy method.

  1. Fill a circle with red, on its own layer

  2. Select > None

  3. Duplicate the layer

  4. Apply some Gaussian blur to the top layer

  5. Set the layer mode to "Dissolve"

Another method:

  1. Make a circle selection
  2. Bucket-fill with color
  3. Select>Invert
  4. Filter>Noise>Spread... and give the maximum extent of the "spill"

You can also use Select>Feather to blur the selection a bit to avoid the sharp edge:
