Package 'crayons'

Title: Color Palettes from Crayon Boxes
Description: Provides color palettes based on crayon colors since the early 1900s. Colors are based on various crayon colors, sets, and promotional palettes, most of which can be found at <https://en.wikipedia.org/wiki/List_of_Crayola_crayon_colors>. All palettes are discrete palettes and are not necessarily color-blind friendly. Provides scales for 'ggplot2' for discrete coloring.

Heuristics for Color Distances and Locations

Description

  • pick_colors() places each color into RGB space, clusters them with k-means, and returns the colors nearest each cluster center.

  • color_order() reorders colors so that subsequent colors are far from each other in RGB space.

  • color_distance() calculates pairwise distances in RGB space between colors.

Usage

pick_colors(hex, n)

color_distance(hex)

color_order(hex)

Arguments

hex

a character vector of hexadecimal colors

n

the integer number of desired colors

Value

a character vector that is a subset of hex, or a matrix of distances for color_distance()

Examples

pick_colors(crayons$standard, 10)
color_order(crayons$standard)
color_distance(crayons$standard[1:4])

Crayon Color Scales for ggplot2

Description

Crayon Color Scales for ggplot2

Usage

scale_color_crayons(palette = "standard16", which = NULL, ..., reverse = FALSE)

scale_fill_crayons(palette = "standard16", which = NULL, ..., reverse = FALSE)

scale_colour_crayons(
  palette = "standard16",
  which = NULL,
  ...,
  reverse = FALSE
)

Arguments

palette

palette from names(crayons) to use

which

numeric indices of colors to use. NULL by default.

...

arguments passed on to ggplot2::discrete_scale()

reverse

Should the vector be reversed? Default is FALSE.

Value

A ggplot2::Scale

Examples

library(ggplot2)
ggplot2::mpg |>
  ggplot() +
   geom_point(aes(displ, hwy, colour = class)) +
   scale_color_crayons(palette = 'original')

ggplot2::mpg |>
  ggplot() +
   geom_point(aes(displ, hwy, fill = class), pch = 23, color = 'transparent') +
   scale_fill_crayons(palette = 'original')
