The Standard Object Color Spectra database for color reproduction evaluation(SOCS)is developed and introduced in this paper. SOCS is developed to evaluate the color-sensor quality of image-input devices properly. The total number of colors in SOCS is up to 49672, and divided into eight categories. Analyzing and managing such a huge database is difficult, and by only reading the boring data, features of SOCS database are hardly to be found. Therefore, we developed a visualization software called SOCS Viewer. Using it, failures or anomalies of color data or gamut data are much easier to detect and examine than using the text data files. The analytic results demonstrate its usefulness.
