Please Help Me Decide!

Now that the bathroom is done, the project has spilled over into the hallway outside of the bathroom.  The walls and trim of the hallway are looking a little dingy compared to the bright and shiny newness of the bathroom.

The hallway is a bit dark.  Right now it has light khaki colored walls and white trim, the same as almost every other wall in the house (boring!).  The hallway leads to the kids' rooms, so I want it to be light and bright.

I have three choices for the walls and I need you to help me decide. 

Choice #1:
Do the same thing as the bathroom: white beadboard wallpaper, white chair rail, and blue-gray paint above.

Choice #2:
Paint horizontal stripes on the wall using the blue-gray color and a slightly lighter (or maybe darker?) color on the paint chip.  I like this wall from Ten June:

Choice #3:
Choice #3 is a combination of the previous two.  I would paint the upper walls a super-light grayish white, put up a white chair rail, and then paint the light gray and darker gray stripes below the chair rail.  It would look something like this:
