wavelength2RGB: Convert Wavelength to RGB Colors

In raim/platexpress: Inspection and Analysis of Microbial Growth and Gene Expression Data

Description

Converts wavelength in nm (visible light: 380:780 nm) to RGB. NOTE that this is not a fully correct spectrum, see Details.

Usage

wavelength2RGB(wavelength)

Arguments

wavelength

the wavelength in nm to convert to RGB

Details

implemented following the java code posted at http://stackoverflow.com/questions/1472514/convert-light-frequency-to-rgb . Also see http://www.fourmilab.ch/documents/specrend/ for original code and why not all wavelengths can be converted to RGB.
