摘要：
Panoramic scans of two lunar regions (Aristarchus-Herodotus and Plato craters) were obtained with a CCD camera and spectrograph to determine a range of actual color differences. The color differences expressed in color-excess (CE) units and determined as the intensity ratios for lunar features at 440 and 550 nm are mainly less than 0.1(m), The color-albedo dependence is revealed only in separate clusters and is not the same in different parts of each region under consideration. This special feature of crater Aristarchus is confirmed; that is, in spite of its high albedo, the color in the crater is intermediate within the general range of color differences.
