Bathroom Improvement

I’ve got a new apartment taht is virtually a blank canvas… All white walls and even a creme colored sofa… I’m not worrying about the kitchen yet, but I do want to go ahead and decorate my living, bed, and bathroom… If you have any ideas or know where I can find any accessories that fit what I am looking for, please let me know!
For the Bedroom, I was thinking pink and green and white…. Though I’m not sure where I could find a comforter and accessories and which should be my main color and which should be accents..
For the livingroom… I don’t know, I was thinking the whole jungle//palm tree look that is so in right now? But again, I’m at a loss for how to pull it off and where to find the stuff to decorate it reasonably.
For the bathroom… I’ve posted asking for help, but only got two answers. I’m really open for whatever I guess. Things I DONT WANT– Navy blue, duckies, froggies, flowers.

What color paint do you recommend for the walls in a small, windowless bathroom? Right now the walls are painted two shades of dark blue in a striped faux finish. The floor is white tiled with a navy blue border along the outside. The vanity and commode are white with country french navy blue toile design handles. Any color blue just looks too dark. Is yellow my only option?
