A lighting device including a blue solid state emitter, at least one yellow-green or green lumiphoric material, and at least one red or red-orange solid state emitter can simultaneously provide high color fidelity (e.g., high CRI Ra), high color saturation (e.g., high Qg), and high efficiency (e.g., lumens per watt). A subcombination of blue and yellow-green emissions is provided within one or more specified regions of a 1931 CIE chromaticity diagram. By providing sufficient green content, increased saturation can be active with relatively a short wavelength red or red-orange source while maintaining high color fidelity and efficacy. A mixture of green and yellow lumiphoric materials may be provided.
