IMO, the cabs and furniture need to coordinate, but not necessarily match. For example, we have white perimeter cabinets in the kitchen with merlot colored hood & island. Kitchen is open to family room with 2 built-ins in a slightly off white color. Cubbies are just around the corner from kitchen and can be seen through the doorway--they are also slightly off white. There is enough distance between the whites that you don't notice they don't match--they just coordinate. Our master bedroom furniture has a mahogany finish with antiqued gold pulls, the master bath has espresso vanities with antique pewter pulls and you can see from one room into the other. Again, they are just far enough apart that you really don't notice the difference & they coordinate. Stained furniture can be coordinated with painted vanities/cabinets & vice versa. Unless you're planning something totally outlandish, I think you'll be just fine. Hope this helps!

Yes, I think pink is a beautiful color for a master bedroom! The trick is picking the right pink and then balancing it with other elements that are not overly feminine. I love pink and brown together, or black. When choosing a grownup ink go to the brown section in your color deck. As you move up to the lighter colors you will see what I refer to as dirty pinks. These are softer, more pleasing pinks that men can love.

What color headboard do you have? What color grey for the walls? Sounds lovely!

You may want to start saving inspiration rooms you love; it will really help if you have a direction. I would purchase the rug fist vs bedding and cushions so you have a style to build on. Be sure to use various colors, patterns and textures so it feels more interesting The headboard is high and I think art above each night stand would be more complimentary and use small brass lamps for a modern look. You could add the sign on another wall If you need a bedskirt, a more tailored style would feel more modern Dresser and tv wall - mirror, plant, chair, art, baskets
