Francesca Samsel participated in the Color Mapping Panel at IEEE Vis 2015. The panel highlighted optimal solutions for designing and building color maps in visualization applications and presentations. The panelists represented artists, software engineers, cartographers, color scientists, perceptual psychologists, and visualization researchers who have contributed effective solutions to applying color to data visualization. Each panelist highlighted their perspective as well as tips and tricks for color map solutions. Drawing on perspectives from many disciplines, the panel identified gaps in the understanding about the use of color in visualization and identified future research directions.
