Generates n colours sharing base's own hue and saturation, swept
linearly through HSL lightness from lightness[1] to lightness[2]
– a monochromatic ramp from near-black, through base's own hue, to
near-white (or whatever narrower lightness range is supplied).
Usage
palette_tonal(base, n = 5L, lightness = c(0.1, 0.9))Arguments
- base
A single colour, used as the palette's shared hue and saturation.
- n
A single positive whole number: the number of colours to return.
- lightness
A length-2 numeric vector, each between 0 and 1: the HSL lightness of the first and last returned colours. Default
c(0.1, 0.9)avoids sweeping all the way to pure black/white.
