4. Metal. Metal affects mental clarity and logic. The presence of metal within a room can be felt in personal characteristics such as organization, focus, righteousness and analytical abilities. When surrounded with too much metal, you can be seen as chatty, overly critical and prone to speaking without thinking. When there's too little metal, you may notice a feeling of quiet, cautiousness and lack of focus.

When enhancing a space with metal, add:

• round or oval shapes
• anything made of metals, including iron, aluminum, gold or silver
• rocks and stones
• white, gray, silver or light pastel colors
