Multiwavelength solid-state lamps with an enhanced number of rendered colors

A lighting method, comprising:

• configuring at least two sets of visible-light emitters using a plurality of test color samples including more than fourteen test color samples resolved by an average human eye and a reference light source dissimilar from the at least two sets of visible-light emitters, each set of emitters having a primary color, wherein the configuring includes selecting at least one of:
• the primary colors or relative fluxes generated by each set of emitters to maximize a number of the plurality of test color samples for which, when illuminated using the light source having a predetermined correlated color temperature instead of the reference light source having the same correlated color temperature:
• chromaticity shifts resulting from use of the light source instead of the reference light source are preserved within corresponding regions of a chromaticity diagram, each region defined by a color at a center of the region and a predetermined chromaticity variation value from the color at the center of the region;
• and
• lightness shifts resulting from use of the light source instead of the reference light source are preserved within a predetermined lightness variation value.
