This Neon symbol was made by placing two neon tubes alternatively. The club and spade symbols were made of Blue neon, ( a neon tube infused with mercury vapor gas. The hearts and the diamond symbols were made of Red neon, ( a neon tube infused with a little amount of helium gas)
The characteristics of these symbols
Clubs : Otherwise known as trefoils, clubs represent many things like fall, winter, night, darkness, male, fire, energy, will, wealth, work, luck, and happiness.
Hearts : represent the warmth of spring and summer seasons and the power of light. They are the center of life and the world. In the Tarot, hearts can also symbolize knowledge, love, life from water, and fertility, and in fortune-telling, joy.
Spade : represents a leaf of the "cosmic" tree, and thus life. Along with its companion suit, clubs, spades represent fall and winter and the power of darkness. In the Tarot, they symbolize intellect, action, air, and death.
Diamond : represent warmth, light, femininity. In the Tarot, they symbolize earthly matter, money, courage, and energy, but fortune-tellers often associate diamonds with spitefulness and annoyance.
