Objective evaluation of color change of various medicines. The results of objectively evaluating the color change of various medicines after the test of photostability was shown. Mean gray value was estimated using ImageJ. The color change of various medicines was evaluated after storage for 1 day to 28 days in three lighting conditions (Daylight-color LED lighting (△), bulb-color LED lighting (□) and fluorescent lighting (○)) in UV-cut plastic bags (a-d), brown light-shielding plastic bags(e-h), and normal plastic bags (i-l)
