Selective Coloring

In this tutorial I am going to show you how to change colors of only one part of a picture. First open your image:

Now zoom in the picture by pressing Ctrl and + at the same time, then select the Polygnal Lasso Tool and select around the object you want to change the color of.

Next, go to Image » Adjustments » Hue/Saturation and select the colors you want. This is how mine turned out.
