Continuous color scales using the diverging color scales in Tableau.
See scale_colour_tableau() for Tabaleau discrete color scales,
and scale_colour_gradient_tableau() for sequential color scales.
Usage
scale_colour_gradient2_tableau(
palette = "Orange-Blue Diverging",
...,
midpoint = 0,
na.value = "grey50",
guide = "colourbar"
)
scale_fill_gradient2_tableau(
palette = "Orange-Blue Diverging",
...,
midpoint = 0,
na.value = "grey50",
guide = "colourbar"
)
scale_color_gradient2_tableau(
palette = "Orange-Blue Diverging",
...,
midpoint = 0,
na.value = "grey50",
guide = "colourbar"

for (palette in head(names(palettes))) {

# If you need to reverse a palette, use a transformation
