Step 11:
Now that the selection is back in place, go to the bottom of the Layers panel and click on the Create a New Layer icon (it looks like a page with a turned-up
corner and is just to the left of the Trash icon) to create a new blank layer at the top of the layer stack. Next, we’re going to steal a color from the
background, but not just any color—we want one that predominantly stands out. To me, that light blue in the columns on the right jumps out, so switch to
the Eyedropper tool (press the letter I on your keyboard), and then click it somewhere inside that blue column to select that color as your new Foreground
color (you’ll see a circle appear onscreen, with a gray ring around it, as seen here). Now, to fill your selection with this color (yes, it should still be in
place), press Option-Delete (PC: Alt-Backspace) and it fills just your selected area with this light blue Foreground color (as seen here). Then, press
Command-D (Ctrl-D) to Deselect. Of course, that fill completely covers our subject on the layer below it, but we’ll fix that.
