Optimization of individual display primary attributes often drives primary choices in different directions. For example, expansion of color gamut favors narrow spectral bandwidth saturated primaries and minimization of observer metamerism favors broadband primaries. To characterize the tradeoffs between the different attributes in primary design for three-primary and multiprimary displays, we propose a multi-objective optimization framework for determining the complete range of available primary choices that optimally negotiate the tradeoffs between the metrics for the different attributes.
