Hi there WirelessG,
Iím Mr. Jay with The Home Depot out in Chicago.
Itís a bit hard to tell from the pictures and Iím not sure if it is the same vendor that you used, but we carry Custom Building Products as our grout manufacturer. We actually have 48 different colors for you to pick from, and we do have both take home charts as well as chalk samples for you to look at in the store that best represent the color.
Iíd suggest bringing a few pieces in (as large as piece as possible) to one of our stores, and we can help match it up for you. Bare in mind though that new grout and old grout, even of the same color, will look a bit different due to age and wear.
Let me know if you have any other questions,
- Mr. Jay [Iím a Home Depot Store Associate, trained and authorized to help people on the Internet]
