Turbo, an Improved Rainbow Colormap for Visualization
While arguments in the blogpost are mostly compelling (perhaps the most important to me is Jet/Turbo being far more high-contrast in the "colder" regions), I see Inferno as vastly superior still, mostly for the same reasons it was superior to Jet. All these colormaps are intended to represent one-dimensional gradient, as in "from hot to cold" and it is completely obvious when looking at Inferno. Jet & Turbo give a false impression of non-one-dimensionality. It might be a matter of being used to the colormap in question, but Jet is as old and common as it gets, and it still is not self-evident to me that the dark red is hotter than the very light yellow. I mean, obviously I know that, but I will tell you instantly without thinking what is the hottest and coldest regions on Inferno image, and I am significantly more likely to make a mistake when I'm tired with the Jet (and, presumably Turbo — for the same reasons).
