While other methods separate the creation of colors from their assignment, our approach takes data characteristics into account to produce color palettes, which are then assigned in a way that fosters better visual discrimination of classes. To do so, we use a customized optimization based on simulated annealing to maximize the combination of three carefully designed color scoring functions: point distinctness, name difference, and color discrimination. We compare our approach to state-of-the-art palettes with a controlled user study for scatterplots and line charts, furthermore we performed a case study. Our results show that Palettailor, as a fully-automated approach, generates color palettes with a higher discrimination quality than existing approaches. The efficiency of our optimization allows us also to incorporate user modifications into the color selection process.</dcterms:abstract> <dc:creator>Lischinski, Dani</dc:creator> <dc:contributor>Chen, Xin</dc:contributor> <dcterms:rights rdf:resource=""/> <dc:contributor>Deussen, Oliver</dc:contributor> <dcterms:available rdf:datatype="">2021-02-19T12:33:40Z</dcterms:available> <dc:contributor>Cheng, Zhanglin</dc:contributor> </rdf:Description> </rdf:RDF>
