Health, Wealth, and Abundance

Blue represents the water element in Feng Shui design. Feng Shui practitioners associate the water element with luck and good fortune. Using water features in a home signifies wealth, abundance, and prosperity.

Sadness and Melancholy

In Western culture, the phrase “feeling blue” describes a state of sadness or depression. This association may stem from ancient West African cultures where mourners would dye their garments indigo blue to represent their suffering during death ceremonies. 

Blue in Color Therapy

The significance of blue is also evident in color therapy. Most walk-in tubs and showers feature blue LED lights for therapeutic purposes. Blue’s calming effects lower blood pressure and pulse rate and improve sleeping patterns.

Natural blue light also boosts alertness and helps memory and brain function. But, nighttime exposure to blue light can disrupt the circadian rhythm (sleep-wake cycle).
