A very bright and attractive colour and the colour of trust and responsibility!
After seeing this colour the first thought that comes to my mind is ocean and the sky... both are far apart from each other, firstly ocean signifies depth which in turn tells us that colour blue is hiding a deep meaning. Secondly, sky signifies of freedom... which tells us that it is free from all the boundaries... "let the blue sky meet the blue sea and all is blue for a time."
