We are using Calstone AB Stone Classic Collection retaining wall blocks in a brown color and looking for a lighter colored concrete color to blend. We do have brick work in the overall yard, but I am not looking for a pinky undertone. Ideally looking for a light beige undertone to match. The color from the chart that looks best is San Diego Buff, but online it can look pinky. Any have experience that can comment and share photos please?! Thank you!
