Description:
Wavelength creates Color objects given the wavelength or the frequency of the light rather than the usual RGB or HSB. instead of: Color c = new Color(255, 0, 0); use the frequency in nanometers, and gamma 0.0 to 1.0. (gamma is intensity/brightness.) Color c = Wavelength.wvColor( 400.0f, 0.80f ); The visible range of the spectrum is 380..780 nanometers. Smaller is bluer. Use frequency in Terahertz with fColor.
