#> Warning: n too large, allowed maximum for palette Blues is 9
#> Returning the palette you asked for with that many colors
show_col(brewer_pal("div")(5))
show_col(brewer_pal(palette = "Greens")(5))
# Can use with gradient_n to create a continuous gradient
cols <- brewer_pal("div")(5)
show_col(gradient_n_pal(cols)(seq(0, 1, length.out = 30)))
