The color of the Hydrangea is determines by the PH of the soil. Ask at your local garden shop or look it up on line which soil ph determines what color. Here in SC most of our bushes turn out white or light pink because our soil is acidic. Out west most soils are alkaline you can test your soil with an inexpensive soil test kit or send a sample to your local college extension program to get it tested for ph and a list of what to do to get your plants to bloom another color.
