This sounds like a rust fungus infection.
The best course of action will be to use wettable sulfur and dolomitic lime together. This will kill off the infection, along with condition the soil from the treatment.
The leaves should rarely be any color other than dark green for this shrub unless it gets much colder than normal. Otherwise, this will be an issue that needs correcting. In this case, when the infection has been cured, the shrub will continue normal growth.
