Wavelength to rgb color conversion

Calculates rgb values from spectra based on human color matching functions

Usage

w_length2rgb(w.length, sens = photobiology::ciexyzCMF2.spct, color.name = NULL)

Arguments

w.length

numeric Vector of wavelengths [\(nm\)].

sens

chroma_spct Used as chromaticity definition.

color.name

character Used for naming the rgb color definition.

Value

A vector of colors defined using rgb(). The numeric values of the RGB components can be obtained using function col2rgb().
