Variance suppressing uncertainty palette

Returns a palette function that turns `v` (value) and `u` (uncertainty) (both between 0 and 1) into colors.

pal_vsup(
  values,
  unc_levels = 4,
  max_light = 0.9,
  max_desat = 0,
  pow_light = 0.8,
  pow_desat = 1
)

Arguments

values	Color values to be used at minimum uncertainty. Needs to be a vector of length `2^unc_levels`.
unc_levels	Number of discrete uncertainty levels. The number of discrete colors at each level doubles.
max_light	Maximum amount of lightening
max_desat	Maximum amount of desaturation
pow_light	Power exponent of lightening
pow_desat	Power exponent of desaturation
