There are times when finding the average color of something is useful. It could be to create a backdrop, for color correction, or to make a palette to smooth out uneven colors. It’s easy to do it too. Here’s how: Make a selection around the area where you want to average the colors. Press Command-J (PC: Ctrl-J) to copy the selection to a new layer. Command-click (PC: Ctrl-click) on the layer thumbnail to load the copied area as a selection, and then choose Filter>Blur>Average to create a solid color of the average of all the colors in the selection.
