— Successful color‐management of projection systems depends on knowledge of their characteristics. In this study, two typical portable projectors were characterized. The projectors are based on different technologies, liquid‐crystal display (LCD) and digital light‐processing (DLP). Measurements were made with a spectroradiometer. The properties measured were spectral characteristics and the intensity of the primary and white colors, basic colorimetric characteristics, inter‐channel dependency, tone characteristics, color‐tracking characteristics, spatial non‐uniformity, dependency on background, and temporal stability. Based on the characterization results, the possibility of color‐management of the tested projectors is discussed.
