Select Color Range (PSE 13+)

"Select Color Range" is a handy tool for selecting continuously colored areas.

1. If your image contains similarly colored areas, you may need to pre-define the selected area roughly, e.g., with the Rectangular Marquee. While a selection is active, the "Color Range" only works within the selected area (fig. 2).
   
2. Run "Select Color Range" command (fig. 1). The "Color Range" dialog that opens contains a black and white preview thumbnail of the currently selected color. The white areas indicate "selected" range; the black ones mean non-selected.

   Tip: If "Select Color Range" command is missing in the list, check the "Show All Commands" gadget (fig. 1/2).

3. In the image window, click on the color you want to select.
   
4. In the dialog box, activate "Add to sample" eyedropper and click in several other places to add more tints to the selection (fig. 2). To remove a color range from the selection use "Subtract from sample" eyedropper.
   
5. Adjust the tool's sensitivity with the "Fuzziness" slider (fig. 3).
6. When ready, click "OK" to commit the selection.
