Usually L'Oreal Paris Excellence, because it seems to last longer on the gray. Sometimes I go with Feria if I want to use a brighter color. My hair growing up was strawberry blonde, but it darkened some in my college years to maybe a light copper brown. I'm finding the lighter colors are easier to blend into the grays when it grows out. My gray hair is actually bright silver, so they really show up.
I think that tone was the reddish brown, but not totally sure.
