There's a reason that white walls are associated with hospitals; they don't evoke a warm and fuzzy feeling. Instead, white walls can be stale and neutral. There are many reasons you may want to paint your home's interior walls:

• Protect your walls' surfaces. Paint helps to ward off normal wear and tear, as well as any water damage.
• Evoke a mood. Color has a profound influence on our psyche. To be elevated or soothed, painted walls can help you get work done or sleep at night.
• Raise the value of your home.
