Usually the blooms that are more dull in color are the older blooms that are just about done. The more vividly colored blooms are usually the newer blooms that have just opened up or have only be open a day or two. When they are just about done with their bloom life cycle the color gets more dull, then the petals fall off. More buds are usually already forming by this time to bring on new blooms. If some new blooms are bright and some not, then it could be a problem with a fungus or virus affecting the rosebush.
