ASi drums start out a sort-of coppery brown color. With use and time they will eventually acquire a dark blue tint. The coloring shown in your photo is common, and often makes no difference in the image quality. My guess is that it's the beginning of arcing of the primary charge to the drum surface. Preventatively you can keep the primary charge clean and/or replaced. In dirty environments it needs to be cleaned or restrung more often than in cleaner environments. Once the drum is like that there is nothing you can do, short of replacing it. =^..^=
