I used Ralph Laurent "River Rock". It came out very good, makes the walls rough, and far away looks like rock formation...as if you were looking at the huge rock formations in Central Park.
I used gold which has teeny tiny black speckles in it, and I also used the deep moss green which also has the teeny tiny black speckles.
The gallon doesn't go very far, you need a lot. It is not cheap by paint standards. It also has to be painted 2 coats, and not straight up and down, but has to be painted in arch's so as to overlap in certain areas to see the texture.
River rock has a how to video, watch it, it explains everything.
I am very happy with the look of it, as I am an extremely fussy person hen it comes to the house
