> completely arbitrary

You agree that it isn’t “physically accurate”, then… but seem to argue that you shouldn’t be called out for the false title?

It’s fair enough to be called clickbait when you really did score extra clicks with a slick falsehood, surely?

Arguing about colormap choice seems very strange to be – this is such a common practice in astronomy (and other fields!). The vast majority of images you see in published papers apply some arbitrarily-chosen colormap and color scheme. No matter if you look at observational or theory papers, it's very rare to find a real true-color image. And for a bunch of good reasons!

The only difference here is that I don't show a colorbar with explicit color-number mapping, for simplicity sake.
