We have a buff brick home (it has a yellow/cream cast as opposed to white or grey). There is a blacktop driveway in-between it and the retaining wall. The retaining wall is about is about 55 feet long and about 3 1/2 feet high at the highest point and then come down to about 2 1/2 feet, so I would like it to blend in with the house and not detract from the appearance. We have had several estimates and no has really been able to find blocks to compliment it. Right now it is 6x6 treated wood timbers.
