Quantum lighting!

Quantum dots are tiny crystals of semiconductor material that emit light when excited by light or electricity. If you apply thin films containing the quantum dots to the external faces of conventional LEDs, you can change the color of light. Thus you can converts the harsh LED light into warmer and more pleasing, without sacrificing the high energy efficiency typical of LEDs.
Quantum dots are coming! They are already on the market.
