The ggsketch qualitative colour palette

Eight muted ink-on-paper colours led by the package primary (Carolina blue, #7BAFD4), ordered for maximal separation.

Usage

sketch_palette(n = NULL, interpolate = TRUE)

Arguments

n

Number of colours to return. If NULL, the eight anchor colours are returned. Up to eight are taken verbatim; beyond that they are interpolated (or recycled, if interpolate = FALSE).

interpolate

When n > 8, interpolate the eight anchors into n colours (the default). FALSE recycles the anchors with a warning.

Value

A character vector of hex colours.

Details

The first eight colours are returned exactly, so small categorical plots keep their recognisable hues. Ask for more than eight and the palette is interpolated: a smooth colorRampPalette() ramp through all eight anchors yields n distinct ink tones, so the discrete sketch scales keep working for large factors and for quasi-continuous use. Set interpolate = FALSE to fall back to the old recycling behaviour instead.
