Should I use the same color carpet throughout the entire house or can I change it in some rooms?
If you have a small house, keep the flooring colors and materials to a minimum. The fewer the changes, the larger your house will seem. However if you have a large home, you can probably afford to make color changes and materials changes.
In an open floor plan house, it is difficult to change carpet colors because you will into many rooms from any location. But if you live in an older house, you probably have many separate rooms and this makes it easier to change flooring colors and materials without them being too noticeable. However, if you are considering re-sale value, the same color carpet throughout the house is the best choice.
