scale_color_okabe_ito(aesthetics = "colour", order = 1:9, alpha = NULL, ...)
scale_fill_okabe_ito(aesthetics = "fill", order = 1:9, alpha = NULL, ...)
scale_edge_colour_okabe_ito(
  aesthetics = "edge_colour",
  order = 1:9,
  alpha = NULL,
  ...
)
scale_edge_color_okabe_ito(
  aesthetics = "edge_colour",
  order = 1:9,
  alpha = NULL,
  ...
)

Arguments
