What Colour to Paint the New Place?

I've been busy the last couple of days painting the kids rooms the colours they chose - now it's time to pick a main colour for the house.

I don't know what I was thinking letting a 7 year old pick her own colour from the wall of paint chips but I did. Painting her room was like being inside a huge pink bubble gum bubble. The theme of her room is Rock n Roll - specifically her favorite - Avril Lavigne. I'm going to try to find a small black crystal chandelier and some large black poster frames. I'm going to paint a rock n roll tattoo image in black on the main wall and a guitar in black on a small side wall. I'll stain the closet doors as black as I can and put really big crystal door handles on them.

My son's room is grey - concrete grey. He wants an urban themed room. I'm going to put up some brick wall paper, find some metal for one wall and some chain link fencing to make frames with. The closet door will be stained black and I'll use old skateboard wheels as handles. The skateboard will be affixed to the back of the door. I found a street light lamp to put in the room and I still need to find a cool urban light fixture.

Any ideas or links to products for these two themes would be appreciated.

Now for the big decision..... which colour to paint the rest of the house. Which colour do you like? This picture and the picture at the top of this post are of the same colours, just in different rooms and different lights. Funny how light works on colour.

Darkest colour is Belgium Sweet
Medium colour is Toffee Crunch
Lightest colour is Bison Beige

The Grey is out... too cold.
