I selected colors I believe would be a good fit for the design of your space! These are just recommendations to start with. I saw you had a Behr sample which looked great next to the cabinet sample! I'd look at your paint colors, wallpaper, tile and cabinetry samples all at one time to ensure the color tones of the paint work with your selected finishes!

For the blue accent color, I recommend it along the closet wall and wrapping that same color into your bedroom (behind the headboard) and along to the front entry of the master bedroom. This wall will be a great foundation for your bedroom! All other walls in your bathroom/bedroom can be painted a neutral color!

I'd suggest using an eggshell finish on the walls and a flat finish on the ceilings.
