The default color scheme in ggplot2 i.e., scale_color_hue picks evenly spaced hues around the hcl (Hue-Chroma-Luminance) color wheel starting from 15.

You can emulate ggplot default colors using the following function:

  gg_color <- function(n) {  hues = seq(15, 375, length = n + 1)  hcl(h = hues, l = 65, c = 100)[1:n]}

For example:

To plot a bar plot by emulating 5 ggplot colors:

  n = 5cols = gg_color(n)y <- 1:5barplot(y, col = cols)

Output:

  ORn = 5cols = gg_color(n)dev.new(width = 5, height = 5)plot(1:n, pch = 16, cex = 2, col = cols)
