Soccer fanatics bleed the colors of their team. All the colors of a club, city or country are specifically chosen for their symbolic meaning that roots back to the begining. I have found

Black is associated with power, elegance, formality, death, evil, and mystery.

White is associated with light, goodness, innocence, purity, and virginity. It is considered to be the color of perfection.

Red is the color of fire and blood, so it is associated with energy, war, danger, strength, power, determination as well as passion, desire, and love.

Orange combines the energy of red and the happiness of yellow. It is associated with joy, sunshine, and the tropics. Orange represents enthusiasm, fascination, happiness, creativity, determination, attraction, success, encouragement, and stimulation.

Yellow is the color of sunshine. It's associated with joy, happiness, intellect, and energy.

Green is the color of nature. It symbolizes growth, harmony, freshness, and fertility. Green has strong emotional correspondence with safety.

Blue is the color of the sky and sea. It is often associated with depth and stability. It symbolizes trust, loyalty, wisdom, confidence, intelligence, faith, truth, and heaven.

Purple combines the stability of blue and the energy of red. Purple is associated with royalty. It symbolizes power, nobility, luxury, and ambition. It conveys wealth and extravagance. Purple is associated with wisdom, dignity, independence, creativity, mystery, and magic.

Soccer is a game of passion and of history. When we see these colors in a teams new kit, it usually brings up some type of emotion. This is what some of the major brands are trying to do today. The designer of a jersey will look deep in to the teams past and also the city or countries past as well to design a jersey that pays tribute to both the team and its founding city or country.

So there is a reason after all for all these crazy colors and designs.
