Penelope, Alexis, and Myself are positioned on top of our school's sign. Penelope's bathing suit is a gorgeous hot pink, my straw hat is quite cute, and Alexis's tie-dye shirt is colorful. I wanted each of these items to be the attention grabbers of the picture so I used the Layer menu, new adjustment layer, hue/saturation.

Then you adjust saturation to negative 100.

I zoomed into Penelope and used the brush tool, with black as the top color and white as the bottom, and painted the bathing suit. Her suit turned its natural hot pink color, and when I accidentally painted her skin, I switched to white on top/black on bottom and painted on the skin, which turned it to gray scale again.

And the final result:
