What's your colour?

At the moment we are redecorating. We have been wanting to do this since we moved in Feb 2010.
We started with the kids rooms which have been finished...well, except for the windows and doors! (we like to do things backwards)

Now, we are painting the hallway, lounge and dining (they are pretty much all linked up). This was stemmed from my son and I both being frustrated with the mess that his wardrobe is always in. We decided to build in shelves at either end, with one end having a short bar and a shelf for shoes, under which we will put a basket for his soccer ball etc.
As my husband wants to paint the inside the same as the rest of the house we have ended up choosing colours.

We started with 4 white colours - then i promptly discovered i actually hate white walls! In some houses it works but generally when i walk into a house with white walls i feel a bit uninspired. There's no personality.
I understand that white is clean and modern, but it's not me.
We love our colours. So after my scowling all afternoon husband went back to the paint shop for more samples and came back with 4 creams.
Now this is me! It feels warmer, not so stark or prestine. I am not a tidy person - though every now and then i hate mess and just have to have things organised. I have organised mess! (mostly)
And two young children, an 8 month puppy and a cat, so prestine is not our house!

This got me to thinking about how other people feel about colours, what makes them choose the colours they do, what colours would present my characters and why.
We are actually going to use the same colour in one of my favourite pictures that i used in a scene for my story The Price of Passion, it's the greeny brown on the walls. Resene Mondo! I'm very excited about this!

So, colours.
I love bold, bright colours that represent the personality of the people in the house. But then i do love autumn colours which to me are so warm and inviting. So earthy tones too.

What colours do you like for decorating? How do you choose?
