Espresso Exterior Stain?

Hello. I am looking for an exterior Espresso colored stain to use on some cedar window shutters. You see this color used on a lot of indoor furniture these days. I can't find this dark of an "exterior" stain on the shelf at any of the stores. Can anyone tell me what big box stores will mix a stain for me or if this is even possible? Or if you have a link to somewhere I can purchase exterior stain in the Espresso color, that would be helpful. Heck, even if you know what stains to mix and the ratios to achieve my goal would be great. Much appreciated. 🙂
