Abstract
Some embodiments provide a program that provides a graphical user interface (GUI). The GUI includes a display area for displaying an image that includes several pixels. Each pixel includes a set of pixel values in a three-dimensional color space. The GUI includes a first selectable GUI item for activating a color masking tool (1) for selecting a set of pixels in the image and (2) for defining a three-dimensional volume to encompass the pixel values of the set of pixels in the three-dimensional color space. The three-dimensional volume serves as an approximation of a rectangular cuboid that has at least one rounded corner. The GUI includes a second selectable GUI item for applying a color correction operation to the image by modifying pixels in the image that have pixel values encompassed by the three-dimensional volume in the three-dimensional color space.
