Qualitative scales

Qualitative scales contain a discrete set of distinct colors with no implied order.

gg_color_swatches(title="ggplot2 default discrete")
gg_color_swatches(title="colorblindr Okabe-Ito") + scale_fill_OkabeIto()
gg_color_swatches(title="colorblindr Okabe-Ito w/ black") + scale_fill_OkabeIto(use_black = TRUE)

The colorbrewer scales are all called via scale_fill_brewer(type = "qual", palette = "name"), where name is the name of the palette, e.g. palette = "Accent".

gg_color_swatches(title="colorbrewer qualitative: Accent") + scale_fill_brewer(type="qual", palette="Accent")

The continuous viridis scales are all called via scale_fill_viridis(option = "name"), where name is the name of the palette, e.g. option = "viridis".
