Fighting against Rainbow Colormaps everywhere!


Scientists co-opt our visual system to convey numerical data in a format that's easily understandable using spatial and color variation to capture details of the underlying data. A “colormap” transforms the set of numbers into a pattern of plotted colors.

When done poorly, this transformation introduces well-established visual artifacts and obscures the underlying detail. Furthermore, certain colormaps create images that are inaccessible to readers with anomalous color vision (i.e. colorblindness).

Unfortunately, widely-used rainbow colormaps, like "jet", face these issues but are pervasive in the scientific literature. Jetfighter aims to prevent this by detecting problematic colormaps in publicly available pre-print manuscripts and then contacting the authors, if necessary.
