Here's a quick Photoshop tip: Use the Color Replacement Brush (nested in the Brush tool on the Tool Bar) to change the color of an object or subject in an image.
Below is a shot I took this past weekend on my Plymouth, MA workshop. The workshop was organized by Amy Davies, who heads up the Plymouth Photography Club.
Above is my processed/enhanced image.
I used the Color Replacement Brush to change the color of the model's dress - picking a color (using the Eye Dropper tool and the Color Picker) from the wall.
After changing the color the dress, I softened the picture using the Pastel filter in Nik Color Efex Pro, and then added a Vignette filter, also in Nik Color Efex Pro.

P.S. I teach this kinda stuff on my workshops.
