Examples

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))

cowplot::plot_grid(
  gg_color_swatches(8) + scale_fill_OkabeIto(darken = 0.6),
  gg_color_swatches(8) + scale_fill_OkabeIto(darken = 0.4),
  gg_color_swatches(8) + scale_fill_OkabeIto(darken = 0.2),
  gg_color_swatches(8) + scale_fill_OkabeIto(darken = 0),
