I want to select by colour but I only want to select one 'island of colour', not all pixels of the chosen colour.

For example, in the image below, how would I select-by-colour:

  • only the red colour island (area) labeled "A", or
  • only the white area labeled "4"?

I found the answer - press "U" for the "Fuzzy Select Tool".

    Note that if you look carefully, not all pixels on the edges are selected, because they are a blend of the shape color and the other shape or background color. If you are creating images the problem can be avoided by using a layer for each shape.
