A user can create, modify and select colors for creating digital artwork using the interactive palette interface. The interactive palette interface includes a mixing dish in which colors can be added, removed and rearranged to blend together to create gradients and gamuts. The mixing dish is a digital simulation of a physical palette on which an artist adds and mixes various colors of paint before applying the paint to the artwork. Color blobs, which are logical groups of pixels in the mixing dish, can be spatially rearranged and scaled by a user to create and explore different combinations of colors. The color, position and size of each blob influences the color of other pixels in the mixing dish. Edits to the mixing dish are non-destructive, and an infinite history of color combinations is preserved. ## Claims ### Claim 1 A computer-implemented method of providing an interactive palette interface (GUI) in a digital painting application, the method comprising: assigning a first set of attributes to a first pixel group, the first set of attributes including a first reference coordinate point, a first color value, and a first size value, the first reference coordinate point defining a location of the first pixel group within the GUI, the first color value defining a color of the first pixel group, and the first size value defining a number of pixels included in the first pixel group;
