Portinari color palette

Source: R/portinari.pal.R
portinari.pal.Rd

Returns a vector of hex colors from a Portinari palette.

Usage

portinari.pal(
  palette = "cafe",
  n,
  type = c("discrete", "continuous"),
  direction = 1,
  colorblind = FALSE
)

Arguments

palette

Name of the palette. See portinari.palettes() for choices.

n

Number of colors. Defaults to the length of the palette (or of its colorblind-safe subset when colorblind = TRUE).

type

"discrete" returns distinct colors and errors when n is larger than the palette. "continuous" interpolates. When omitted, the type is chosen from n.

direction

1 (default) for the standard order, -1 to reverse it.

colorblind

If TRUE, only colors that remain distinguishable under protanopia, deuteranopia and tritanopia simulation are used. See portinari.cvd.check().

Value

A character vector of hex colors with class "portinari_palette".

Details

Palettes come in three categories (see portinari.palettes()): qualitative palettes for unordered groups, sequential palettes for ordered values, and diverging palettes for values around a meaningful midpoint. Discrete palettes pick n colors that suit the category: the most distinct colors for qualitative palettes, evenly spaced steps for sequential palettes, and balanced steps either side of the light center for diverging palettes. Continuous palettes interpolate the full palette in CIELAB space.
