I was looking at some of the manipulated photos featured in This Is Colossal and I got to wondering if I could restore the photo to the original colors. Using the Photo Tool > Photo Hue Tool, then reducing the saturation, and brightness brought most of the original color back. The edges of the cactus should not be as blue, but more the color of the cactus itself. With some more work I could hand mask the edges and modify the color.
