Got two cans of a very dark gray semi-solid wood stain but when applied to yellow pine boards it is too dark. What do you suggest?

I was looking for a weathered look, gray or really a bark color that would blend right into the trees. Could I combine a color to get a bark color like a taupe that has some
tan in it? Please help. It looks like I really wanted a light tan gray color. Could I add a color to achieve this?
