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 […]
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 […]
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 […]

I recently added to my Matlab File Exchange function, Perceptually improved colormaps, a colormap for periodic data like azimuth or phase. I am going to briefly showcase it using data from my degree […]
At the end the series The rainbow is dead…long live the rainbow! I introduced CubicYF, a rainbow-like color palette with a slightly compressive, monotonic increasing lightness profile. The red color is missing from the palette because green […]
