The colour of hydrangeas is affected by the pH of the soil - soils with a low pH (up to about 5.5) are acidic soils and will produce blue or purple flowers. Soils with a high pH (above 5.5) are more alkaline and flowers tend to become pink as the pH increases.
Many modern Hydrangeas are bred to be more inclined to either blue or pink, but in my experience they usually eventually revert to the above 'rule'.
