Staring at Stripes

Inspired by this bathroom from Young House Love, I decided to paint stripes in our guest bath, but i need your help!!

The inspiration

Which two colors would make the best to use for wide stripes in our half bath??? 

Let me know which two colors, based on their numbers, you think would make the best stripes.  Is it #1 and #2?  Or perhaps the closeness of #1 and #4 would work best?  What about the yellowish tone of #3 with another color??
