4/// This macro draws all the high definition palettes available in ROOT.
5/// It generates a png file for each palette and one pdf file, with a table of
6/// content, containing all the palettes.
7///
8/// In ROOT, [more than 60 high quality palettes are predefined with 255 colors each](https://root.cern/doc/master/classTColor.html#C06).
9///
10/// These palettes can be accessed "by name" with `gStyle->SetPalette(num)`. num
11/// can be taken within the enum given in the previous link. As an example
12/// `gStyle->SetPalette(kCividis)` will select the following palette.
