The authors explain a new way to create color schemes (colormaps) for data visualization by extracting colors from artworks or pictures. These colormaps include detailed brightness changes, which help highlight features or lines in the data more clearly. They show that using the natural and appealing colors from an image can make it easier to understand complex data. Their approach is interactive and aims to be more efficient than existing tools.

Abstract
Color transfer functions (i.e. colormaps) exhibiting a high frequency luminosity component have proven to be useful in the visualization of data where feature detection or iso-contours recognition is essential. Having these colormaps also display a wide range of color and an aesthetically pleasing composition holds the potential to further aid image understanding and analysis. However producing such colormaps in an efficient manner with current colormap creation tools is difficult. We hereby demonstrate an interactive technique for extracting colormaps from artwork and pictures. We show how the rich and careful color design and dynamic luminance range of an existing image can be gracefully captured in a colormap and be utilized effectively in the exploration of complex datasets
