In tropical seas, the first impression is stunning. It’s a firework of colours competing in vividness and intensity: red, yellow, blue, green and even black and white.
In a neverending gracious dance, the colors mingle, disappear, twirl or just wander before our awed gaze.
The display is breathtaking, but is beauty the only reason for colours? Is there a hidden agenda? Is there such a thing as a colour code?
