Claim Text:
1. A method of grouping a plurality of light emitters, comprising: generating emitter raw spectral power distribution data for each of the plurality of light emitters; estimating front of screen (FOS) spectral power distribution data for each of the plurality of light emitters from an application specific transmission characteristic corresponding to a filtering property of a transmissive component and the emitter raw spectral power data for each of the plurality of light emitters; selecting a first portion of the plurality of light emitters using a first region of a multiple axis color space that includes International Commission on illumination (CIE) 1976 and that corresponds to a first FOS spectral power distribution, the region proximate a predefined point on the multiple axis color space and comprising a major axis including a first length and a minor axis including a second length that is less than the first length; selecting a plurality of other portions of the plurality of light emitters using a plurality of other regions and having a substantially similar size and shape as the first region, at least one of the plurality of other regions being adjacent the first region, and wherein the major axis defines an angle of less than 45 degrees from a vertical axis of the multiple axis color space.
