Blue is a magnificent feng shui color. It ranges from gentle aqua blue to the blue-green of the ocean to the deep indigo blue of the crown chakra. In feng shui, we associate blue with the clear sky and the healing, refreshing waters. Feng shui-wise, color blue belongs to the Water feng shui element. You can bring the needed blue color as wall color, art depicting blue, or various decor items. Gentle blue is an excellent feng shui choice for a home office or a child's study, especially as a ceiling color. Several studies have shown that children performed better under the blue-colored ceiling then under the typical white color one. Light blue is also the feng shui color of harmonious expansion and gentle growth, while darker blue evokes the feng shui energy of deep calm and serenity. Depending on your feng shui priorities, you might want to introduce some deep blue elements into your bedroom to promote better sleep or a gentle playful aqua in the living room of a big and busy family. Deep blue should be used sparingly in the feng shui areas of South, Northwest and West areas of your home or office, and freely in the North, East and Southeast. One of the most calming feng shui combinations is the combination of the blue and white colors, as it brings the energy of unlimited sky and happiness to one's home.
