Basement Redo

Our basement is serioulsy lacking.  It's completely white....except for a bright red terra cotta floor.  There are lots of cool built ins and a fireplace but it's seriously lacking character.

Here's what it looked like when we moved in.....it still pretty much looks like that.

I have no idea what to do with this floor (and replacing it or removing it is not an option).  I feel like terra cotta always looks cool in resorts in the Mexican Riviera but not so much in a basement in western North Carolina.

I've been doing some research into what other people have done with terra cotta floors and it looks like I'm either going to have to go full on kokopelli southwestern down there or pretty much leave it white.

I'm thinking I'm going to do some type of off-white with maybe some sort of stone accent.

I like how this one is sort of white but not really.  I also like the dark trim and hope that it's not too dark in a basement with only one window.

I'm also thinking of doing some sort of rock accent wall on the fireplace wall and around some of the built ins. I saw in Lowe's the other day some sort of faux rock overlay thing that I think might work.

Any ideas? There's only one window down there and it's pretty dark, so nothing too crazy.
