Home Depot carries a wide variety of colors and types of stains. I believe the best approach to selecting a stain to match what you are looking for is to go to the Home Depot paint department. In the paint department is a display with different types of woods, with a variety of stain colors. This way you can see how each stain will actually appear. If while you are there you have more questions the knowledgeable paint staff will be very happy to help you choose and put together all the materials you need to make the your contribution to this special day a HIT.
Congratulations to your brother and his bride!
If you wish to send a photo of how they turn out I would love to see them.
