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.
