Get perceptual-distance of continuous-palette from reference color

Get perceptual-distance of continuous-palette from reference color

pev_data_distance(.fcont, hex_ref = NULL, n_panel = 40,
  include_cvd = TRUE)

Arguments

.fcont	object that can be coerced to pev_fcont, when called with a numeric vector with values between 0 and 1, returns the corresponding (hex-code) values.
hex_ref	character single hex-colors to act as the reference, default value is the beginning of the range of the continuous-palette, i.e. at x = 0.
n_panel	numeric number of panels into which to discretize the domain (0 to 1) of the continous-palette.
include_cvd	logical or character, indicates to include data for for color-vision deficiency. Possible character values: "none", "protan", "deutan", "tritan".

Value

data.frame with variables cvd, x, hex, hex_ref, distance
