You have been given excellent description, especially with the pictures. The stock turns grayish, then greenish, then a brown to reddish color. Then you can use red maple, or brown stain to make the color pop. A combination of red and brown is what I use. However, the color could be anything from light to dark. I usually wipe the stock with a baking soda and warm water mixture, following the use of the Aqua-Fortis, just to neutralize the acid. If you don't do this, the stock might continue to darken with age. I have one rifle, that was not neutralized and it is now as black as an old church organ. I think, it looks good but it is black, and I mean black.
