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. This color is excellent for use in the feng shui bagua areas of East (Health & Family) and Southeast (Wealth & Abundance) of your home or office, as Water energy nourishes the Wood element of these two feng shui areas.
You can bring the needed blue color as wall color, art depicting blue, or various decor items
