Color palettes from Few's "Show Me the Numbers"

Qualitative color palettes from Stephen Few (2012) Show Me the Numbers. There are three palettes: Light, Medium, and Dark. Each palette comprises nine colors: gray, blue, orange, green, pink, brown, purple, yellow, red. For n = 1, gray is used. For n > 1, the eight non-gray colors are used.

Usage

few_pal(palette = "Medium")

Arguments

Value

A palette function. It takes the number of colors n and returns a character vector of n hex colors, and can be used as the palette argument of ggplot2::discrete_scale().

Details

Use the light palette for filled areas, such as bar charts. Use the medium palette for points and lines. Use the dark palette for highlighting specific points or for small and thin lines and points.
