Paul Tol's vibrant Discrete Color Scheme

Usage

scale_colour_vibrant(..., reverse = FALSE, aesthetics = "colour")

scale_color_vibrant(..., reverse = FALSE, aesthetics = "colour")

scale_fill_vibrant(..., reverse = FALSE, aesthetics = "fill")

scale_edge_colour_vibrant(..., reverse = FALSE, aesthetics = "edge_colour")

scale_edge_color_vibrant(..., reverse = FALSE, aesthetics = "edge_colour")

scale_edge_fill_vibrant(..., reverse = FALSE, aesthetics = "edge_fill")

Arguments

...

Arguments passed to ggplot2::discrete_scale().

reverse

A logical scalar. Should the resulting vector of colors be reversed?

aesthetics

A character string or vector of character strings listing the name(s) of the aesthetic(s) that this scale works with.

Value

A discrete scale.

Interpolation

The qualitative color schemes are used as given (no interpolation): colors are picked up to the maximum number of supported values.

Qualitative Color Schemes

According to Paul Tol's technical note, the bright, highcontrast, vibrant and muted color schemes are color-blind safe. The mediumcontrast color scheme is designed for situations needing color pairs.

The light color scheme is reasonably distinct for both normal or colorblind vision and is intended to fill labeled cells.

The pale and dark schemes are not very distinct in either normal or colorblind vision and should be used as a text background or to highlight a cell in a table.

Refer to the original document for details about the recommended uses (see references).
