It looks like the mason did a good job concerning the texture. But the color is way off. Unfortunatly its not easy to match new to old. The good news- Staining morter isnt hard to do if its not sealed. I suggest a few practice bricks and some best efforts at staining them to match, then do the rest. The bad news- it will probably never be pefect and if it is it will show after a few years of all that Texas weather torture.
