Effect of display size on color matching performance

The performance of color matching functions (CMFs) is important for color specification and calibration, especially for modern displays. The interaction between size and primary was seldom investigated. In this study, four groups of color matching experiments were carried out, which included a wide range of stimulus sizes and primary sets. The results suggested that the size of stimulus played a critical role in color matching, especially when the stimuli were produced by displays having different wavelengths for the green and blue primaries. For easy applications, the stimulus sizes can be classified into three categories based on the field of view (FOV)-small (FOV < 4°), medium (FOV between 4° and 10°), and large (FOV > 10°), and the Asano2(2°), CIE 2006 4°, and Asano7(10°) recommended for the three categories respectively.
