Before

After

Summary:
To colorize the haunted house in this project, I used tools such as the Magic Wand, Polygonal Lasso, and the Quick Mask tool. I used the Magic Wand to colorize the big tree on the left as well as the dead trees and branches in front of the house. I used the Polygonal Lasso to colorize some of the trees in the back. The tool I used the most on this project though, was the Quick Mask tool. I used it to do all the house, including the roof, pillars, windows, etc, as well as the sky/backdrop and the rest of the trees on the right side of the photo and to the right. I would say the Quick Mask tool personally is the best one to use in a project like this.
