Depends a lot on the colors of the furniture you already own -- you need to start somewhere. Then you get a coherent feeling from a general overall style plus some shared palette -- that is, you don't need every room to be gray and green, but maybe you either go bright or subdued, colder or warmer colors. Plus, distinct rooms (bathrooms and kitchen) can sort of go their own way(s)...

If you find a color you really like you can do it in varying shades. Other wise paint sample brochures are great at giving examples of colors that compliment each other.

Will you use your current furniture? Do you have area rugs? If you have rugs or will be getting rugs, consider their colorations before painting the walls. The rooms shown appear to have some version of white on the walls, which helps brighten those rooms. The problem may be easily solved by bringing your floor and table lamps to the new house and see if the rooms look better with more lighting.

Hi and Congrats on your new home!

I recommend going a bit lighter on the walls, an off-white or pale cream will definitely brighten the space. Also, I think painting the living room ceiling a soft/pale shade of any color, (my collage is blue/green- Benjamin Moore's Glacier Blue), and carrying that color throughout your home through accessories, backsplash, walls, etc., will unify the spaces. If it were me, I would paint all the mouldings white to match the white crown.

Hope this is helpful. Good Luck!

Copied from houzz article: Start by picking a color for the biggest, most centrally located room. This will most likely be your living room or kitchen, and it's a great place to start working on your whole-house palette. If picking colors has been stressing you out, choosing a soft, neutral hue for the main room will make picking the other colors easier.

The comments after the article are great too.... choose a fabric for the palette, etc..

Natalie's color is so nice and mixes with other similarly non-saturated colors:

BM Swiss Coffee would look good with the floor and the trim

If you mean opening removing some walls and/or opening up some of the walls by widening doorways and/or creating pass through windows, your first step is to determine which walls are weight bearing walls.

If you mean "connect" as decorate so the house has the same feel from room to room, start with deciding the paint color. Not fond of that stark very light walls with very dark trim look.

Unless your decorating taste leans toward Mediterranean -- or something else that requires that stark dark/light contrast, consider painting all of dark wood a quality flat true white, leaving your wall color options entirely open.

If decide to not paint all that dark wood white, consider painting all the wall a darker shade of off white or pale brown -- the tan without the pink or yellow hue.

Adding mini-blinds to all the windows -- inside the window frames -- in every room is a good first decorating step that helps protect your privacy and would begin to link the decor of all the rooms. Then, choosing the same or coordinating fabric for all additional window coverings would as well.

Thank you very much! This helps alot.

Your trim is stunning (and a huge, difficult job to paint well) and fits with the architecture of the house. Miniblinds don't. High windows give privacy without full coverage in most locations - you can wait on drapery because that is part of choosing how much color and pattern you want in your décor.

A neutral color can be used in several different shades (look at some of the strips that take a color from white to dark) and still provide flow. So, for instance, here you might use a deeper shade in the small entry - it has no natural light except when the door is open . . but gives contrast back to the main room.

You might go lighter in a stair hall because visibility there is a safety thing.

Here I see some terrific opportunities for new sconces / lighting and the wonderful archways and trim give you real architectural interest. Congrats on your new home!

I agree with @libradesigneye. I wouldn't paint your woodwork or add miniblinds.

It's a matter of taste, but I prefer the original wood. And I'm not a "wood at all costs" person.

Maybe beautiful color of Natalie's, muted more, could one room have that paint / and use that color as accent in another room.... with current wood stain.

Houzz article I posted? one method was pick a color for 1 room - say you happen to like this red - DR for instance, only - use red in other rooms....
