The focus of this paper is to evaluate the ability to reproduce preferred colors for mobile displays under ambient illumination condition. Mobile liquid crystal display (LCD) and active matrix organic light emitting diode (AMOLED) are used and 3D gamut volume in CIECAM02 QMh space is utilized to take absolute perceptual attributes into account. The 'degree of inclusion (DOT)' is calculated from the quantity of colors included within display gamut volume among the preferred colors of 1260 from six categories of image database. As a result of this evaluation, the ability of LCD to reproduce preferred colors is similar with a level of AMOLED due to its high brightness under general office environment.
