The idea of this type of Color Correction is to isolate a specific object’s colors and alter them in contrast to the rest of the image. For example, say you want one person to appear slightly brighter in a scene than the rest of the characters. This type of color correction would be done by matting the specific segment out of the rest of the image and then altering it using a 3-Way Color Correction. You are going to have to use the most advanced color altering tools your editing software has because you will need to get the full range of possible colors for it. Likewise you are going to have to use other effects and tools to change the borders of the specific object in the image. Again, this is different with different options, but usually Soften, Edge Feather, and Edge Thin tools should be the most effective.
