beauty is beauty, plain and simple.
If her hair was beautiful, whether gray, it is still beautiful. If her hair looked BETTER colored, than gray, then go with which looks better.
I have a friend with the most beautiful gray hair. It is naturally the most artistic blend of 'salt and pepper' that looks awesome with the trend of 'highlights and lo-lights' and weaves, yet it is both natural, and gray. Not only that, but it is thick, soft and 'moves' like in the Pantene commercial. It is not dull, or dry. It's cut in a style that is upbeat and flattering, and she has a 'young' face.

I'm a natural redhead. My dad always said, "redheads don't gray, we just fade", and that is true. I used to be a very dark redhead, and it has merely lightened.
I envy those who gray beautifully. While men gray so attractively (never cared about Sean Connery UNTIL he grayed!)
so do many women! If it looks good (and that's the key), flaunt it!

It really depnds on the woman. The choosing for me is about much more then the physical aspect, so i can't see grey hair being any type of factor. I like to try and find someone to spend some time with that is more then just .......... hummmm ....... skin deep? I know there's a word i'm looking for but i can't think of it at the moment.

On the other hand, and part of your question, age IS a rather large factor in making a choice for me. I love an older women.

Like snowblind, I prefer mature women.
hair color would be meaningless.
In fact, I might get a bit of a kick (as a grandfather) if I were with somebody's grandmother (and it's happened to me...we ended the session showing each other photos of our grandkids).

Who says kids have all the fun?

P.s. My grandkids were prettier.

No difference to me.  I am interested in the total person.  I do not want to spend time with people that do not have confidence in themselves.  None of us was created to look the same.

I agree with Sedona,  I have met some very wonderful women in their 30’s that had beautiful gray hair.  The women had a great confidence in themselves.  They were a lot of fun to be with and we carried on some very interesting and intelligent conversations.  I associate gray hair with wisdom. I do not mind people doing highlights, but not a complete color change.  I actually prefer natural all of the way.

Because I am a member of the "gray hair club" (and have been since age 30), I admire a woman who is able to accept aging gracefully....and has the confidence to appear in public as nature intended.  The most relevant response was illustrated in a New Yorker cartoon about 10 years ago--two 70ish women having lunch at a fancy restaurant; one says to the other, "Mabel, my you are looking well, and all of you looks the same age".  Most women are able to accept men with gray hair and wrinkles as distinguished; we men should should have that wisdom.

I would welcome it, after all I have gray hair. Mature women are beautiful!

Hey, I've always been into older babedom.
Grey hair is a turn on for some of us.
