This is a color-blind friendly, qualitative scale with eight different colors. See palette_OkabeIto for details.

scale_color_OkabeIto(aesthetics = "colour", ...)

scale_fill_OkabeIto(aesthetics = "fill", ...)

scale_OkabeIto(aesthetics, use_black = FALSE, order = 1:8,
  alpha = NA, ...)

Arguments

aesthetics

aesthetic mappings

...

common discrete scale parameters: name, breaks, labels, na.value, limits, guide, and aesthetics. See discrete_scale for more details.

This code is copied and modified from colorblindr to remove the darken param, which is only available in unreleased colorspace 0.4.1.

Examples

library(ggplot2) ggplot(iris, aes(Sepal.Length, Sepal.Width, color = Species)) + geom_point() + scale_color_OkabeIto()
ggplot(iris, aes(Sepal.Length, fill = Species)) + geom_density(alpha = 0.7) + scale_fill_OkabeIto(order = c(1, 3, 5))
