Purple is the color of meditation so it works well in rooms where you want to think introspectively, like bedrooms, studies or libraries.
Purple is used in the treatment of epilepsy, scalp disorders, mental and nervous disorders and tumors. It is also believed to help those who suffer from migraines or insomnia. Purple also strengthens the lymph system and immune system and helps purify the body. Too much purple suppresses emotions or provokes excessive feelings of arrogance. Balance it with yellow.
