Wavelength range to rgb color conversion

Calculates rgb values from spectra based on human color matching functions

Usage

w_length_range2rgb(
  w.length,
  sens = photobiology::ciexyzCMF2.spct,
  color.name = NULL
)

Arguments

w.length

numeric vector of wavelengths (nm) of length 2. If longer, its range is used.

sens

chroma_spct Used as the chromaticity definition.

color.name

character Used for naming the rgb color definition(s) returned.

Value

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