For the inside of a house, particularly if it lacks a lot of natural light, the pastel shades are the way to go. Now, I'm wondering if you know this, but there is a way of determining the EXACT opposite colour, if you feel like doing to adjacent wall in matching colours. Here's how's it's done:
Take a small piece of paper of any shape, paint it with one of the colours. Once done, place this coloured piece of paper on a white sheet of paper. Stare at the coloured shaped piece unless you eyes get tired of it. Then whip it aside quickly but with your eye's focused on the area the coloured piece was a moment before. Keep looking. Within a few seconds the EXACT opposite colour will come up, showing up on the white piece of paper you left below.
This is your subconsicous mind giving your eyes natural relief. So if you want a room that's easy to live in, but you want to entirely different colours, try this method.
The effect is very short-lived. It's also bad for your eyes to stare at anything...especially this computer. You need to blink every couple of seconds. If you stare at anything long enough, it just becomes a blur and disappears until you blink once again.
I usually like mostly white with an occasional splash of deep color - I painted one wall in our living room eggplant a while back and another wall in our bedroom burnt coral. I really liked them, but after a while you get tired of it. Right now my favorite kitchen color is red - perks me up, gets me cookin' and makes me hungry. For me, I like to change colors quite often (every other year or so).
It depends on the room and how much light is already there. A medium to dark shade of green for instance is warm and adds wonderful contrast/color to a room - or maybe just 1 wall with some accents to go with it - but can be complimented by a light yellow or light gold color in the same room - or adjacent to it.
It is a matter of the whole concept of the house in my humble opinion - what furniture you have (dark or light) and what other fabrics, rugs, pieces you have in the room - and again, how much natural light each room has.
By far though, I prefer not heavy, dark colors but light and airy as it gives your house a feeling of happiness!
It depends on the purpose of the room and the atmosphere that I want to create. For example, for the home theatre room, I prefer dark oak walls, soft leather seating and accents with deep red and splashes of vanilla. The flooring is a lush chocolate brown carpeting (which really helps with sound performance). The oak walls are decorated with tapestry hangings, which also help with the sound.
On the opposite end of the scale, for the sunroom, I prefer white ceilings, pale yellow walls and natural rock in warms tones for the flooring. The furniture is rattan style around glass tables. It's light, airy and welcoming.
I think that for the most of the house light would be preferred, even with a lot of windows and /or skylights. But for the master bedroom I'd use darker colors. It is better to sleep in the dark. Just make sure you have enough lighting when you need to do some work there.
I like a mix, with some bright or dark accents against lighter colors.
My grandma always had the interiors of her homes painted all white (even over the wood trim!) as she felt it gave a clean feeling but to me it was like being in a blank space or on the set of a scifi movie.
Then there's the friend of mine who has a house that looks like it's a Pottery Barn catalog page. I can't tell if it means she has her own style or not.
This is a question that has been bothering me for a while now about which colour wine is more popular, do you prefer a glass of red or white? No being cheeky and putting 'both' or rose, we need a definitive answer here...
