flower colour shows the pH of soil
acidic soils produce blue flowers
neutral soils produce very pale cream petals
and alkaline soils results in pink or purple

In these species the exact colour often mirrors the pH of the soil; acidic soils produce blue flowers, neutral soils produce very pale cream petals, and alkaline soils results in pink or purple. This is the caused by a color change of the flower pigments in the presence of aluminium ions which can be taken up into hyperaccumulating plants

more Aluminum content in the soil = less pH value –> blue color.

Flower color, which is variable depending on soil pH, will be pink in alkaline soil, with acidic conditions turning the flowers blue.

Acidic soils produce blue flowers, neutral soils produce very pale cream petals, and alkaline soils results in pink or purple.

Changing a hydrangea from pink to blue entails adding aluminum to the soil. Changing from blue to pink means subtracting aluminum from the soil or taking it out of reach of the hydrangea.
