Home makeover for bedroom!

Ok ladies so my SO and I want to give our room a makeover. Well our bed is on the floor so we are planning on getting a queen size bed and bed frame. Well right now our bed is king size and our blanket is like old people (his grandma gave us it). Well I don't know what color theme we should do that will match the wall color and floor. We can't paint it sadly since we are renting the place. What color bed sheets, bed blanket, pillow, bed frame shoild we get to match? We both suck at home decor and decorating. (Sorry if it looks dirty!) Also the wall is like creamish I guess you can say or tan. The pictures were to show the wall color and the colors around.
