Arguments

n

Number of colors to return.

Details

In many of these palette names, the color in the upper left corner is given first, and the color in the

lower right corner is given second.

The ��brewer.*�� palettes use ��bin�� (binary), ��div�� (diverging), ��qual�� (qualitative), ��seq�� (sequential)

for the horizontal and vertical directions.

The ��arc.bluepink�� palette uses white in the lower-left corner, which makes it difficult to see the

difference between low values and missing data on maps.

The ��census.blueyellow�� palette is slightly different, in that one direction uses lightness, and the

other direction uses hue (yellow, green, blue).

The ��vsup.*�� palettes are Value-Suppressing Uncertainty Palettes.

We strongly discourage using ��vsup.viridis��, because the horizontal axis has changes in brightness,

which are confounded with the changes in brightness in the vertical axis.

These palettes are all deliberately chosen to be discrete.

Bivariate color palettes can be difficult to use and interpret. Please be careful.

Value

A vector of colors as hex strings.
