If you're referring to the getter flashing inside the tubes, brown (often with a rainbow hue) is normal for some tubes, particularly older ones. Differences in getter deposits is a function of getter material, method of activation/vaporization, and ambient conditions (e.g. condition of the vacuum environment).
