Comment (by pierreroudier): Those palettes all share the same core characteristics: colorful, perceptually uniform, and robust to colorblindness. In my view, I like to switch between these depending on the data I am representing -- for example I tend to prefer `magma` or `inferno` to `viridis` to represent say temperature. I've found it useful to have access to those different palettes and adapt to the context -- or sometimes it might just boil down to personal preferences I suppose (how does one use `magma` and not think of Dr. Evil in Austin Powers??). More background/illustrations of those palettes: https://cran.r-project.org/web/packages/viridis/vignettes/intro-to- viridis.html#the-color-scales Suggested comments: For inferno: {{{ # perceptually uniform and sequential # contains black, red and yellow # color table developed for Matplotlib (default in 2.0) # license of the original data: CC0 # original authors: Nathaniel J. Smith, Stefan van der Walt, Eric Firing # created from cpt-city mpl inferno (r.cpt2grass -s) }}} For magma: {{{ # perceptually uniform and sequential # contains pale yellow, purple and black # color table developed for Matplotlib (default in 2.0) # license of the original data: CC0 # original authors: Nathaniel J.
