I don't know what Revere Pewter would look like with the browns you have, but I've seen pictures of it with walnut and calacatta marble and it look very nice. Buy a sample and paint a board with several coats and set it in the room to see if you like it. It is a Benjamin Moore color.

You don't need ONE wall to be a color. The room has four walls. You don't have high ceilings, so what??! I have no clue what you mean by " The front of shelves." The biggest mistakes made are those that come from over thinking the space, the colors, the POPS , the accents. One color on the front and another on the back You want teal? Paint the BACKS the bookcases in teal. change the tile to a simple light tone stone or tile. Maybe a soap stone surround, if you want something darker. . Paint the mantel white.Then? Minimally add the teal in other accents. A rug with a dab of it..... art ...etc. The point here is you give the room a POINT of view. Design is editing. It's to pick a loose thread from a sweater and follow the unravel . It's a combo of no fear, and a little restraint, all at the same time. I am not a fan of the half way I can't make up my mind/ I can't commit look. : ) If yu want the backs painted? Echo the color elsewhere. or WRAP the room in a color ( no, not teal )

The cabinets look to be in very good condition. I wouldnt be painting them. I would be buying accessories in some colors and maybe an area rug on the table, and get some pretty curtains, or some type of window treatment to give it a personality. Right now, it looks like a nice kitchen in a house where no one lives.

I am doing tape lights for all of my under cabinet lighting but the open shelves are in a kitchen bar. I guess I thought I would switch it up but what do I know lol Would I not have to have a strip roughtered out to put the tape light in so you can't see it? Could that be done without removing the shelves?
