Blonde and never dyed my hair. Now have grey and white hairs. What do I do?

I'm blonde and have never had highlights. I usually just use Sun In (I know!) every few months to lift my colour. I've now started getting white and grey hairs coming through. I'm 50 in not ready to go grey/white yet so wondered what you would advise in terms of colouring my hair to cover the greys. I have absolutely no clue as I've never had my hair coloured at the hairdresser. My hairdresser said I could just started herring it coloured to cover the greys but I don't know what colour to go for. Do I try and change my hair colour to a lighter or darker blonde?
Sorry for the blurred out faces in my photos!

Twas me that recommended the superdrug wash in/out honey blonde and it works for me! It's a colour shampoo (lathers up) and you can leave it on for up to 35mins. It fades with each wash and gone in 3 or 4. I don't think op has anything to lose in trying it?

I’ve used the Superdrug honey blond on a section of grey hairs by my ears, they turned orange. Avoid for grey hair.
