1. A light source, comprising:

  • one or more light-emitting elements in each of at least a first, a second and a third colour, a combined spectral power distribution thereof defining a spectral concavity having a minimum located between about 550 nm and about 600 nm; and

    a light-excitable medium configured and disposed to absorb a portion of the light emitted by one or more of said light-emitting elements and emit light defined by a complementary spectral power distribution having a peak located within said concavity;

    wherein an optical quality of the light source output is improved by a combination of said complementary spectral power distribution with said combined spectral power distribution.
