Color Palettes from Crayon Boxes

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.

crayons

crayons provides crayon-based color palettes. For nostalgic uses, consider combining with ggrough or roughsf.

These palettes are not necessarily (and unlikely to be) color-blind friendly. For public-facing work, consider a color-blind friendly package, such as Cory McCartan’s wacolors.

Installation

You can also install the development version of crayons from GitHub with:
