From layers I selected a New Adjustment Layer. Layers>New Adjustment Layer>Hue/Saturation. This opens a layer with a mask. Because I only want to adjust the blue sky at this point I went to the "Select Menu" and chose "Color Range". This opens up a new window and using the eye-dropper + selection tool I was able to select only the blue sky and water areas to adjust. Returning to my Hue/Saturation layer I moved the saturation slider to the left to remove any of the orange color and reveal the blues.
