Create HCL parameter-set

Source: R/hcl_param.R

This follows the colorspace scheme.

pev_hcl(type = c("qualitative", "sequential", "diverging"), h1,
  h2 = NULL, c1, c2 = NULL, l1, l2 = NULL, p1 = NULL, p2 = NULL,
  cmax = NULL, fixup = TRUE)

Arguments

type

character indicating type of HCL palette.
h1

hue value in the HCL color description, has to be in [0, 360].
h2

hue value in the HCL color description, has to be in [0, 360].
c1

chroma value in the HCL color description.
c2

chroma value in the HCL color description.
l1

luminance value in the HCL color description.
l2

luminance value in the HCL color description.
p1

control parameter determining how chroma and luminance should be increased (1 = linear, 2 = quadratic, etc.).
p2

control parameter determining how chroma and luminance should be increased (1 = linear, 2 = quadratic, etc.).
cmax

Maximum chroma value in the HCL color description.
fixup

logical. Should the color be corrected to a valid RGB value?

Value

Object with S3 class pev_hcl

Examples
