In a recent post titled Unweaving the rainbow, Matt Hall described our joint attempt (partly successful) to create a Python tool to enable recovery of digital data from any pseudo-colour scientific […]
Oh, the new, perceptual MatplotLib colormaps….. Here’s one stunning, recent Truecolor image of Pluto from the New Horizons mission: Below, I recolored using two of the new colormaps:

In the first post of this series I argued that we should not build colormaps for azimuth (or phase) data by interpolating linearly between fully saturated hues in RGB or HSL space. A first step […]
In New Matlab isoluminant colormap for azimuth data I showcased a Matlab colormap that I believe is perceptually superior to the conventional, HSV-based colormaps for azimuth data, in that it does not […]
The other day I stumbled into an interesting article on The Guardian online: The medieval bishop who helped to unweave the rainbow. In the article I learned for the first time of Robert […]
In the comment section of my last post, Steve asked if I had code to generate a Surfer.clr file from my Matlab colormaps. Some time ago I did write a […]
Spectral lightness rainbow Quick post to share my replica of Ethan Montag ‘s Spectral lightness colormap from this paper. My version has a linear Lightness profile (Figure 1) that increases monotonically […]
