Hello,

Thanks for your question. I'd be happy to make suggestions for you. Any of the color ideas you've listed could look great with the surfaces already in the bathroom. But, because your bathroom window faces north, I would lean toward warmer colors. A north facing window will bring in a lot of gray/blue light, so a warm green could be a great solution, and any gray would need to be on the warm side. Blue also could work, but I would keep it pure, and stay away from a blue/gray color.

Here are suggestions of paint color to sample in the room.
