Once again, I want to defend the Ritz residences a little bit. It seems obvious that the architect wanted to put up something with upscale finishes but plain enough not to compete with or detract from the glorious deYoung Building. In that regard, most of the pictures seen here don't show the actual surface of the addition which appears to be something like terra cotta and textured so that, in real life and up fairly close, it looks a lot more interesting than most of the pictures I've seen suggest:
Note the texture:
It actually reminds me a lot of some of the "blond" brick buildings I saw put in as a child in the 1950s and I suspect that may have been the architect's intention--something to contrast with but also coordinate with the red brick of the deYoung.
