Abstract
Provided are devices and methods for grouping light emitters and devices including the same. Embodiments of such methods may include selecting a portion of the light emitters using a region of a multiple axis color space that is configured to represent each of a plurality of colors as at least two chromaticity coordinates. The region may be proximate a predefined point on the multiple axis color space and includes a major axis having a first length and a minor axis having a second length that is less than the first length.
