We manufactured the product, but did not do the installation. The pebble is our "French Tan" "Perfect Pebble". It looks like they put a strong enhancer on it. We often use "bone" when grouting pebble projects
Thank you,

forgive me but what is a strong enhancer?

When I look at this product on the mesh- no grout. It does not look like the photo. The photo shows more gold and color to the stone. On the mesh it just looks like white stone. Why is that?

As natural stone there is a fair bit of variation on within a pebble tile. Certain sealers will enhance the color of the product and often give a stronger variation between stones. Certainly their is no substitute for getting a sample piece to make final determinations for yourself as photo editing/lighting etc, all effect the look of the final product in an image.
Here are a few other installs for reference
