aitoa.scale.rgb.luminosity: Scale the Luminosity of a Color

In thomasWeise/aitoaEvaluate: An R Package for Evaluating the aitoa Results

Description

The luminosity of a color is scaled in a range of [-1,1], where -1 means black, 1 means white, and 0 means the color at its current luminosity. A value in (0, 1] will make the color brighter while trying to preserve its chromotographical properties. A value in [-1, 0) will make the color darker while trying to preserve its chromotographical properties. See https://stackoverflow.com/questions/6615002

Usage

aitoa.scale.rgb.luminosity(color, scale, limit = 255L, make.int = (limit > 1L))

Arguments

color	the r-g-b vector
scale	the scale value, in [-1,1]
limit	the maximum permitted value for each rgb-coordinate: defaults to 255
make.int	should the result be converted to integer?

Value

a color with similar chromotographical properties but either lighter (scale>0) or darker (scale<0) complexion.
