Honestly, for the ceiling, I like your current faded blue floor color. It is such a nice soft grayed sky blue that I would match that and use it on the ceiling. The Open Air is very bright and punchy, more of a Carribean feel. Not what I envision for a lake cabin.

What about a soft pinkish clay for the floor as an earth tone to ground and set off the blue overhead? And set off the redwood. You get your blue and pink but a little less in your face.

Look at this gorgeous teal floor. The gloss enamel would be easy to keep clean. Actually probably clear coat sealer.
