When white light, which is composed of all the colors of the rainbow, hits an object, certain wavelengths are absorbed while others are reflected. The color we perceive is the one that is reflected. In the case of blue, it is the shorter wavelengths of light that are reflected, giving us the color we associate with the sky, the ocean, and tranquility.

In Japan, for instance, blue is the color of the sky and the sea, symbolizing infinity and eternity. In Western cultures, blue is often associated with stability and trustworthiness.
