Interior Walls

I'm renovating Mom and Dad's house and while tackling the living room I had an idea. Between the time I applied the coating and the time I sanded and then covered it, I really liked how the raw coating looked. That is to say before sanding. So, for all the interior walls, I really want to leave them in this almost raw state: apply the coating with a large trowel and leave the marks visible. In addition, mix pigments in the coating to vary the colors. Most walls will be a natural lime color with one colored wall per room (depending on the ambiance/theme of the room). Some photos gleaned here and there:
