It is the color of the ocean and the color of the sky—the depth of emotion and the vastness of thought. Clouds and waves. Way up high and way down low. It is flying and swimming, or sometimes, soaring then drowning.
It is found in your sleeping dreams, but also in your waking ones. It is duality and consciousness. Like when you consciously decide to either put on your feeling cap or your thinking cap, as opposed to Red, which represents force, reflex, and involuntary action.
Blue is quietly strong.
It can be sadness or serenity, depending on its shade. It is all forms of water and it is the visible veins under your skin—it is life. And it nourishes, and it soothes, and cools, and calms.
Gentle but powerful. Blue is purpose, clarity and infiniteness.
