The Meaning and Psychology of Blue

Calm and Focus: Blue lowers blood pressure and slows respiration. It is an excellent color for productivity and focus, often used in offices. Communication: Associated with the throat chakra, blue represents clear communication and truth. Sadness: On the flip side, "feeling blue" relates to melancholy and depression, usually associated with darker, greyer shades of blue.
