wavelength2col R Documentation
Convert wavelength to RGB
Description
Converts a given wavelength of light to an approximate RGB color value, using black in the invisible range.
Usage
wavelength2col(wavelength)
Arguments
wavelength
wavelength value (or vector), in nanometers.
Value
Returns a color string or vector of color strings with the same number of elements as wavelength.
