The color blue is often representative of the attainment of awakened mind in eastern philosophy. The color is associated with the sky and the sea, which are seen as symbols of vastness and infinity and the idea that all things are interconnected and interdependent. Being related to the element of water, the color is thought to represent qualities such as fluidity, adaptability, and purification.

In abstract expressionism, the color blue was often used to represent calmness, tranquility, and serenity. Blue was often used in conjunction with other bold colors, such as red and yellow, to create a sense of balance and harmony. One of the key figures in abstract expressionism who made significant use of the color blue was the painter Yves Klein. Klein was known for his monochromatic blue paintings, which he believed were imbued with a sense of the infinite. For Klein, the color blue was a way to create a sense of mystery and evoke a sense of the sublime. Another abstract expressionist artist who made significant use of the color blue was Clyfford Still. Still used blue to create a sense of spiritual uplift and transcendence.

Blue is used in the '108 Series' to introduce a sense of calm and serenity and balance out the chaotic energy of the abstract expressionist artwork.
