Looks like the remodel leans toward modern style. Looks good! To choose a wall color, I'd suggest getting a sample of the flooring, the cabinets and maybe the sofa upholstery and going to the paint store. The staff may be able to show you a few colors. Maybe consider shades instead of curtains? Red is a great accent color for modern accessories and should be easy to find pieces.

I would paint it a crisp clear white then do white lamps and curtains and of course add the red....remove the curtains, I have them in my family room and love them but they are cream, grey, brown, and yellow with a faint blue that is nonexistent visually.

Love the size and feel of this room....it can be a guide for your design.

I know you do not have a red sofa, but note the red in the large art work and the two types of art to add interest and color to the room....simple shades on the windows add a feeling of indoor outdoor space. Whie lamps white mats, round cocktail table to add rhythm to the room too. Add a pair of fun small chairs to shake it up a bit.....you are off to a good start and feel for your room.
