The "standard" palette function in this package takes a numeric input
(0 <= x <=1) and returns a matrix output (LUV coordinates).
Perhaps you want a palette function to return hex-codes; use as_pal_hex().
Perhaps you want a palette function to act as a discrete-palette function;
use as_pal_disc().
It is important to keep in mind that each of these functions returns a function.
as_pal_hex(pal_luv)
as_pal_disc(pal)function with S3 class "cpath_pal_luv"
function that takes a numeric input and returns a color value.
function:
as_pal_hex()return a palette function that returns hex-codes.
as_pal_disc()return a discrete-palette function which takes
an integer input n, and returns n equally-distributed values.
