1. A method of illumination from a light source comprising a primary light emitter, a secondary light emitter different from the primary light emitter, and a shade, the method comprising:

  • providing direct illumination from the primary light emitter by transmitting light emitted by the primary light emitter through a first portion of the shade substantially without modification of the light emitted by the primary light emitter;

    illuminating a second portion of the shade, different from the first portion, with light from the secondary light emitter;

    modifying the light illuminating the second portion of the shade; and

    transmitting the modified light through the second portion of the shade, thereby forming at least a portion of decorative illumination emitted in a direction different from a direction of the direct illumination,wherein the shade comprises a phosphor, and modifying the light illuminating the second portion of the shade comprises converting a wavelength of light from the secondary light emitter to a different wavelength, the converted light exiting the shade and forming at least a portion of the decorative illumination.
