Purple or blue better, blue has the effect of making you sleepy.
purple and black
grey or plum, although plum might be too much purple, you might be able to get away with some kind of green just make sure it contrasts nice with shade of purple
You can paint it with light purple, not very dark and strong purple, it makes the room very dark and gloomy which is bad when you are sleeping. You can also have white, but not so white, you have to balance the white by decorating your room with wood furnitures. This won’t make your room dull and it will have elegant atmosphere.
My favorite purple and gray or u could paint the molding light purple and the wall a lil darker
Both items you picked seem to have a lot of color and pattern. I would keep the wall color more neutral. You can use 1 of the accent colors in the comforter as accent colors your room for pillows and accessories. A dove gray would work well on the walls. Other color choices could include a taupe that has a hint of the purple color. If you choose a gray, try to find 1 that also has a hint of purple in it as well. This will help tie the comforter and the walls together. Hope this is helpful.
