All colours have their significance. For instance red is the colour of passion, strength and fertility; orange represents attraction and kindness while yellow is linked to confidence and joy.
Green, often used by financial institutions, represents prosperity along with health while blue, the colour of the ocean, stands for tranquility, devotion and sincerity.
Purple represents power, white- purity and peace and black, strength and success. Pink is the colour of romance, brown is very grounding while gold is linked to energy, wealth (of course!) intelligence and longevity. Silver on the other hand is the colour of creativity and inspiration.
So knowing all that, which colours would you choose? Maybe a mixture of them all...
