Oh, no idea. It was grown from a cutting from my late grandmother's garden. She always threw her used teabags under the plant to make it purple/blue and I've always done the same.
Signature hydrangeas are very good @pipip. Take a look at their site to get some ideas @Mrs_Miggins. I'm sure they could assist too if you contact them.

Yes Signature Hydrangeas are the ones that keep popping up on google. I'm seeing lots of Annabelle around Kensington and they are lovely too. But I think in that corner it's got to be colours. Like the teabag tip and wonder if coffee grounds might do the same thing? A little project for autumn I think. Thank you everyone!!
Forget about tea bags and coffee. Use a good mulch of compost regularly to improve the soil structure, and accept that the colour is dependent on your soil, unless you're growing a white variety which are unaffected by that. The alternative is a raised bed, purpose built with a suitable soil mix. You really can't fundamentally change the pH of your soil for any length of time.

My old neighbour used to swear by burying a load of old iron nails under a hydrangea to make it blue. I don't know whether there's any truth in it though, although she did have a couple of beautiful blue ones whereas they don't grow at all well for me, in any colour.
Doncaster, South Yorkshire. Soil type: sandy, well-drained
I have Hydrangea paniculata 'Vanille Fraise' The flowers start off a lime green, then turn pure white, the slowly change to a dusky pink - irrespective of soil pH The flowers will be quite a dark pink in a few weeks

Years ago I visited an Hydrangea nursery in Kent - https://signaturehydrangeas.co.uk/ - worth a visit if it's near you.

I'd be inclined to go with the colour you end up with, rather than trying to fight it.
