It's an oil rub stain, custom color.

Gudday, I'm not surprised no-one has responded to you query. This is because a stain is not like paint which is always the same quantifiable colour. A stain will be a different colour on every different kind of timber. On a light timber like pine or cypress a dark stain will look lighter than if applied to a dark timber such as oak (I'm trying to think of American timbers or universal timber types) or walnut, same applies to a light stain.
Because of this unless you know what type of that timber has been used a stain cannot be readily identified visually. To further complicate things, the stain can be diluted or even blended.
I suggest you experiment with a small piece of your chosen timber until you get your desired finish. Keep trying. :-)

7weed1 couldn't have explained it better myself.
