A non-transitory machine readable medium that has a computer program for adjusting color values of an image represented in a color space. The image includes a set of pixels. Each pixel has a set of color values. The computer program receives a user input on a user interface (UI) item for adjusting color values of an image that are associated with a type of content. The computer program identifies a subset of pixels having color values that fall within a range of color values associated with the type of content. The computer program performs a color adjustment operation on the identified subset of pixels.
