The colour blue has very positive and healthy connotations in peoples’ minds, because of its association with the sky and the ocean. Perhaps it is precisely because of this association that it has come to represent peace, calm and tranquility.
It can be strong and steadfast or light and friendly. Almost everyone likes some shade of the colour blue.
Just as "seeing red" alludes to the strong emotions invoked by the colour red, "feeling blue" or "getting the blues" represents the extremes of the calm feelings associated with the colour, i.e. sadness or depression, or the lack of a strong, violent emotion.
Dark blue represents knowledge, power, integrity, and seriousness. This explains why, in Western civilization, those in the upper classes or in high places of political or economic power often wear dark blue "power" suits.
Blue also conveys importance and confidence without being sombre or sinister (hence the uniforms worn by police officers).
Our selection of light and dark blue cufflinks are therefore extremely popular and are perfect for whichever aspects of your personality you wish to convey.
