In the hydrangea "world" a pH of 7 is neutral enough for pink.

Just as rain water is not weak lemonade, a pH of 7 is not alkaline.

Yes Ann theoretically 7 is neutral.

Not theoretically, by definition. By definition alkaline means:

"Having the properties of an alkali; having a pH greater than 7."

Obviously a pH of 7 doesn't qualify. The website you are quoting is
making a common mistake of equating less acidic with more alkaline and
that is not true.
