I have a white mophead (new plant) and two pink mopheads that are ready to be planted. Can they be planted the suggested 3-10 feet apart without the white mophead changing colors?

There can be some color change, but as long as the pH, is neutral, which can be achieved with dolomitic lime. This article will give you more information on the care of these: https://www.gardeningknowhow.com/ornamental/shrubs/hydrangea/mophead-hydrangea-care.htm
