Yes, foundation is difficult when you have gone grey - easier when you are gunmetal and not an indeterminate shade of off-white like me! I found a new product last week: L'Oreal CC cream. It comes in different types, I tried the one "for dull skin" and it comes out of the tube purple but then blends in brilliantly with my own fair skin tone - no tidemarks, no blotches under the eyes, and it's supposed to be hydrating, too, with a SPF 12. I've been using it for a week now, and it has been foolproof. Now I have grey hair I need some added colour without looking too false, and this CC with a little Bobbi Brown blusher looks natural but gives me a healthy glow. I also use mascara, eyeshadow and sometimes eyeliner if I am feeling steady-handed, never to be seen without lippy!
