Thank you for your question, I've looked back through our files and unfortunately do not have the color of grout listed. That being said, if you have a similar Travertine with natural color variation such as in the photo, I think you would be safe with a wide range of grout options. If you would like to attached a photo of what you've done I'd be happy to give my opinion.

could you have removed the 2 pillars to open the space up more... I have a similar structure and want to remove these two obstructive pillars with the adequate support beams

Thank you for your comment, without a full knowledge of your situation it is difficult to give a precise answer. However, in this example you could remove the two columns to provide a more open space. By doing this the horizontal beam would most likely need to be up sized to carry the required load.

Thank you for the prompt response. I sent you some details around my project through your website. Look forward you your response. Thank you!
