ng_palette_d() and ng_palette_c() (respectively for discrete
and continuous palettes) return functions that take an integer argument (the
required number of colours) and return a character vector of colours' hex
codes.
In addition, the functions also recognize the
viridis palettes: "magma" (or "A"),
"inferno" ("B"), "plasma" ("C"), "viridis" ("D"), or "cividis" ("D").
