Wavelength 1.3 (Downloads: 274)
Wavelength creates Color objects given the light wavelength or the frequency 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. .. 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.
