I've tested Revere Pewter in 2 houses in 2 different states and it has not worked for me, but I've seen very pretty spaces painted with it. We used BM Grant Beige for most of the rooms in our current house.

As far as boring and sterile ... use color in your furniture, art and accessories.

I tend to lean towards more traditional, farmhouse styles and want the house to be comfortable, warm, and inviting. As this is our first house, I am new to the whole decorating thing and would like something more classic vs. trendy. The two story ceilings are going to be a pain to paint and I would love to be able to keep the color for several years! The house faces west but the large windows in the back of the home let a lot of natural light in all day.

First of all, I like gray exteriors a lot. Gray houses with white trim. It's what I have and will keep. However, I'm not a fan of gray walls inside the house, esp. if you like a warm feeling. Outside gray has the sun, clouds, sky and flora to smile on it. Inside, not so much. I've been in beautiful homes with lots of windows and all gray walls and it just leaves me cold, very corporate feeling. It was a very contemporary home and still I itched to paint the walls.

People are going to get sick of my saying this, but I recommend a soft white trim (versus stark) and BM Capitol White for the walls, if you like farmhouse style. It is the most gorgeous, creamy, warm white. I just put it on my farmhouse kitchen walls and absolutely love it.

Revere Pewter is lovely color, but read too cold for me in my place (and 12 other grays were too cold for me too; so I mixed my own color and made sure to give it a pretty name so the paint company will have it in their computer for my future references)) All that to say-this or that paint might work totally different in your house, than in mine, and even more than that-in different spots in your house it also might look very different. You'll need to test it in order to know.

Also, I'm with tibbrix-it depends. It depends on the light, it depends on your style. Whether it's classic or trendy also depends more on you-something that you love is classic, something that you temporarily want is trendy. Gray is trendy now, but it's classic too. Every color that exists in nature in abundance is classic, whether people use it heavily right now, or did a century ago. So it really depends on how much you'll like it when you'll see it all around yourself, in your own house.

If you have already some furnishings, or favorite rug, or art you adore, or something to base your palette upon-it will be easier for you to decide on wall color. It's very hard to choose the color for the space without any references. Also it's much easier to find paint color that will work with what you've already got, than to get everything else so it works with your paint color. I did have to do that in my current place, pick everything after wall color-but then I stumbled upon an illustration in a book that inspired me to pick my palette. The moment I felt excited and dreamy about three or four colors together-everything became easier. I did introduce shades and accents and more colors over time, but the base I was building upon was born when I saw that illustration.

No color is boring by itself-color is the part, not the whole. Even though extremely important part.

BTW your floor plan drawing is beautiful-you have a steady hand. I'm envious:) Mine always look like I was drunk when rendering..:)
