Custom color palettes can also be registered to be able to call custom palettes by name. If the optional argument `register = "Custom-Palette"` is set (where `"Custom-Palette"` is the name of your new palette) the palette will be added to the list of available color palettes. Existing palettes can also be overruled. Note that the graphical interfaces (`choose_palette()`) will not use custom palettes. These register-calls can also be added to your local `~/.Rprofile`.
