Source: R/hcl-data.R

TODO: some notes here on is_rgb_limit being applied to non-cvd case.

pev_data_hcl(hex, ...)

# S3 method for default
pev_data_hcl(hex, ...)

# S3 method for character
pev_data_hcl(hex, n = NULL, include_cvd = TRUE,
  ...)

# S3 method for pev_fcont
pev_data_hcl(hex, n = NULL, include_cvd = TRUE,
  ...)

# S3 method for pev_fdisc
pev_data_hcl(hex, n = NULL, include_cvd = TRUE,
  ...)

Arguments

hex

character vector of hex-colors
...

other args (not used)
n

integer number of colors to use for unbounded palette-functions
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, hue, chroma, luminance, is_rgb_limit
