Techniques and systems are described in which signed distance fields (SDFs) can be used to approximate multicolored vector art. A source image, represented as multicolored vector art is received and processed to provide a multicolored planar graph. The graph is processed to provide a SDF mask for each of the colors in the graph. For each of the colors in the graph, a color plane is generated, paired with the corresponding mask and represents the source image's color underneath the mask. Each color plane can be dilated and then one or more of the color planes or masks can be down sampled and then used to synthesize a source image which provides an approximated source image which retains the hard edges of the original image.
