Personally, just looking at the images I think B looks more professional, the others look faded. With A and B I see more of "contrast" in the core of the radial image (though that might arise from a combination of my monitor/eyes, though I usually do quite well in colour perception tests).
I think we really need to see a variety of real examples before we make a decision though, both in application a.k.a different type of datasets, including ones with NaNs; and different graph types, the 3d example will make for a good test as we get the same information twice, from height and colour, which gives us a reference for comparison. With the NaNs Andreas, why did you pick B over C? My eyes see B going to white as well, only C as far as I can tell does not go to white. Looking forward to having a play later :). I wonder what Parula-based colormap would look like if we were to make it linear... one other thing, mpl currently doesn't select good bounds with pure horizontal/vertical lines, making it very difficult (at least for me) to see the perceptual deltas, zoomed in to option_c the line gets completely hidden by the axes...
