1. A method for displaying a mixed color produced by mixing a plurality of individual colorants in a predetermined ratio, the method comprising the steps of:

  • (a) providing a radiation spectrum for a color produced by each individual colorant;

    (b) dividing the radiation spectrum into at least four wavelength bands;

    (c) determining an intensity for each wavelength band;

    (d) transmitting the intensities to a radiation source;

    (e) selecting a narrow band of wavelengths in each of the wavelength bands;

    (f) generating a multiplicity of beams of radiation, each beam of radiation essentially corresponding in wavelength to a selected narrow band of wavelengths and corresponding in intensity to the respective wavelength bands; and

    (g) combining the beams of radiation to display the color.
