library(ggplot2)

Overview

In the ggpalette, there are 6 colours in it. They are pink, orange, navy, grey, magenta and green. You can allow ggplot2 to use the colour palette. There are discrete ggplot palettes and continuous colour scale.

Generate discrete ggplot palettes

Added with ggplot2

p1 <- ggplot(penguins, aes(bill_length_mm, bill_depth_mm, color = sex)) +
  geom_point(size = 2) +
  scale_colour_ggpalette_d() +
  theme_bw()
p1

Use direction = -1 to reserve the order of the palette

p1 + scale_colour_ggpalette_d(direction = -1)

Used for fill aesthetics in ggplot2

p2 <- ggplot(penguins, aes(x = island, fill = species)) +
  geom_bar(alpha = 0.6) +
  scale_fill_ggpalette_d() +
  theme_bw()
p2

Use direction = -1 to reserve the order of the palette

p3 <- ggplot(penguins, aes(x = island, fill = species)) +
  geom_bar(alpha = 0.6) +
  scale_fill_ggpalette_d(direction = -1) +
  theme_bw()
p3
