Extract HSL components

Description

Extract the hue, saturation, or lightness color components from a vector of colors.

Usage

clr_extract_hue(col, space = c("HSL", "HCL"))

clr_extract_saturation(col)

clr_extract_lightness(col)

clr_extract_luminance(col)

Arguments

col	a color object or vector of any of the three kinds of R color specifications, i.e., either a color name (as listed by colors()), a hexadecimal string of the form "#rrggbb" or "#rrggbbaa" (see rgb), or a positive integer i meaning palette()[i].
space	character string specifying the color space where hue is extracted from. Can be either "HCL" or "HSL".

Details

The range of the value are

- hue ranges from 0 to 360. in a circular fashion such that 0 and 360 are near identical. 0 is red - saturation ranges from 0 to 100. 100 is full saturation, 0 is no saturation - lightness ranges from 0 to 100. 100 is full lightness, 0 is no lightness
