Color Lenses

Visualization applications routinely map quantitative attributes to color using color scales. Although color is an effective visualization channel, it is subject to limitations due to display hardware as well as to inherent limitations of the human visual system. We propose a new interaction technique that overcomes these issues by dynamically optimizing color scales based on regions of interest. Color Lenses support efficient navigation into visualizations that are high-resolution in both space and color. We validate our approach with two user studies comparing the Color Lenses with explicit contrast control on visual search tasks.
