Yep, colormaps again! In my 2014 tutorial on The Leading Edge I showed how to Evaluate and compare colormaps (Jupyter notebook here). The article followed an extended series of posts (The rainbow […]
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 […]
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 […]
Why another rainbow In the comment section of my last post Steve Eddins from Mathworks reported that some Matlab users prefer Jet to Parula, the new default perceptual colormap in Matlab, because within certain ranges […]
In What your brain does with colours when you are not “looking”, part 1, I displayed some audio spectrogram data (courtesy of Giuliano Bernardi at the University of Leuven) using 5 different colormaps to render the amplitude […]
