Palettailor: Discriminable Colorization for Categorical Data [article]

Kecheng Lu, Mi Feng, Xin Chen, Michael Sedlmair, Oliver Deussen, Dani Lischinski, Zhanglin Cheng, Yunhai Wang
2020 arXiv   pre-print
We present an integrated approach for creating and assigning color palettes to different visualizations such as multi-class scatterplots, line, and bar charts.  ...  better visual discrimination of classes.  ...  visualizations (e.g., the Colorgorical palettes for scatterplot visualizations).  ...

Color Crafting: Automating the Construction of Designer Quality Color Ramps [article]

Stephen Smart, Keke Wu, Danielle Albers Szafir
2019 arXiv   pre-print
Effective ramps use colors that are sufficiently discriminable, align well with the data, and are aesthetically pleasing. Designers rely on years of experience to create high-quality color ramps.  ...  Our goal is to enable visualization developers to readily create effective color encodings using a single seed color.  ...  ACKNOWLEDGMENTS We thank Maureen Stone and the anonymous reviewers for their feedback. This work was supported by NSF Award # 1657599.  ...

A Study of Colormaps in Network Visualization

Raja Mubashar Karim, Oh-Hyun Kwon, Chanhee Park, Kyungwon Lee
2019 Applied Sciences  
Color is a widely used visual channel for encoding data in visualization design. It is important to select the appropriate type of color mapping to better understand the data.  ...  Specifically, we compare four different single- and multi-hue colormaps for node attributes, and evaluate their effectiveness in terms of task completion time and correctness rate.  ...  Gramazio, C.C. et al. [29] A web-based tool for creating discriminable and aesthetically preferable categorical color palettes.  ...

Accessible Color Sequences for Data Visualization [article]

Matthew A. Petroff
2021 arXiv   pre-print
Color sequences, ordered sets of colors for data visualization, that balance aesthetics with accessibility considerations are presented.  ...  Optimal color sequences containing six, eight, and ten colors were generated using the data-driven aesthetic-preference model and accessibility constraints.  ...  ACKNOWLEDGMENTS The author thanks the thousands of individuals who responded to the color-cycle survey, without whom these results would not exist.  ...
