Hydrangea flower color can change based on the pH in soil.
As the graph depicts, soil with a pH of 5.5 or lower will sprout blue hydrangeas, a ph of 6.5 or higher will produce pink hydrangeas, and soil in between 5.5 and 6.5 will have purple hydrangeas. White hydrangeas can not be manipulated by soil pH, they will always be white because they do not contain pigment for color.
Hydrangea macrophylla flowers can change color depending on soil acidity. In acid soils, chemical reactions occur in the soil that make aluminium available to these plants, turning the flowers blue. In alkaline soils, these reactions cannot occur and therefore aluminium is not taken up by the plant.

Floral pigments in Hydrangea are affected by the presence of aluminum ions in the soil, causing changes in flower color from red, pink, blue, light purple or dark purple. [4]
