In NatParksPalettes: Color Palettes Inspired by National Parks

National Parks Palette Generator

Description

Color palettes inspired by National Parks. Complete list of palette colors and the parks that inspired them can be found on Github. Use colorblind.friendly to check whether palettes are colorblind-friendly.

Usage

natparks.pals(
  name,
  n,
  type = c("discrete", "continuous"),
  direction = c(1, -1),
  override.order = FALSE
)

Arguments

name	Name of Palette. Choices are: Acadia, Arches, Arches2, Banff, Bryce Canyon, DeathValley, Everglades, Glacier, GrandCanyon, KingsCanyon, Olympic, Redwood, SmokyMtns, Yellowstone, and Yosemite.
n	Number of desired colors. If number of requested colors is beyond the scope of the palette, colors are automatically interpolated. If n is not provided, the length of the palette is used.
type	Either "continuous" or "discrete". Use continuous if you want to automatically interpolate between colors.
direction	Sets order of colors. Default palette is 1. If direction is -1, palette color order is reversed
override.order	Colors are picked from palette to maximize readability and aesthetics. This means that colors are not always selected in sequential order from the full palette. If override.order is set to TRUE, colors are selected in sequential order from the full palette instead. Default is FALSE.

Value

A vector of colors.

Examples

natparks.pals("Yellowstone")

natparks.pals("Glacier", direction=-1)

natparks.pals("DeathValley", 4, override.order=TRUE)
