Does Photoshop have a brush that can softly remove a specific color from a photo in a defined area - like a reverse paint brush not just an eraser. Like removing yellow from teeth or changing the tint on skin but only in a specific area. One that you can make hard or soft, big or small, strong or weak so that a color can be removed without affecting the rest of the image. Please! Is there a tool that does this that I am not aware of?
