colourspace_palettes: Colour space palettes

In teunbrand/ggchromatic: Colourspace Scales for ggplot2

Description

These palette functions transform all-numeric colour_spec vectors into colours.

Usage

rgb_palette(x, min = 0, max = 1)

hsv_palette(x, min = 0, max = 1)

hsl_palette(x, min = 0, max = 1)

hcl_palette(x, min = 0, max = 1)

cmyk_palette(x, min = 0, max = 1)

cmy_palette(x, min = 0, max = 1)

lab_palette(x, min = 0, max = 1)

lch_palette(x, min = 0, max = 1)

oklab_palette(x, min = 0, max = 1)

oklch_palette(x, min = 0, max = 1)

Arguments

x	An colour_spec vector with a numeric vector in every channel.
min, max	A numeric(1) specifying the lower and upper limits respectively.

Details

The conversion from colour_spec vectors to colour is powered by the farver::encode_colour() function.

Value

A character vector of the same length as the x argument with hexadecimal colour notation.

Functions

• rgb_palette: Red, Green and Blue colour space.

• hsv_palette: Hue, Saturation and Value colour space.

• hsl_palette: Hue, Saturation and Lightness colour space.

• hcl_palette: Hue, Chroma and Luminance colour space.

• cmyk_palette: Cyan, Magenta, Yellow and Key (black) colour space.

• cmy_palette: Cyan, Magenta and Yellow colour space.

• lab_palette: Lightness*, a* (green-red axis), b* (blue-yellow axis) colour space. Also known as CIE L*ab.

• lch_palette: Lightness*, Chroma*, Hue-angle colour space. Also known as CIE LCh.

• oklab_palette: An OK Lightness, a (green-red axis), b (blue-yellow axis) colour space. Also known as OKLab. Needs farver package version \>2.0.3.

• oklch_palette: An OK Lightness*, Chroma*, Hue-angle colour space. Also known as OKLch. Needs farver package version \>2.0.3.
