hcl
Hue, Chroma, Luminance Color Model

Description

Specifies colors with the hue, chroma, and luminance color model.

Usage

hcl(h = 0, c = 35, l = 85, alpha = 1, fixup = TRUE)

Arguments

h a vector of numbers specifing the hue. This is taken as module 360 where 0 is red, and it goes around the rainbow and returns to red at 360.
c a vector of numbers between 0 and 100 specifying the chroma.
l a vector of numbers between 0 and 100 specifying the luminance.
alpha a vector of numbers between 0 and 1 specifying the opacity.
fixup this argument is ignored.

Details

This is a piecewise linear approximation to the HCL model that is used in R.
Value
returns a vector of color strings corresponding to the given parameters.
The color strings have the format "#RRGGBB" or "#RRGGBBAA" where XX are two digit hexadecimal values (range 00-FF) for the red, green, blue, and possible alpha (opacity) components of the colors.
