Eyes see sea ice. Harmony of colours is much more difficult to be composed than that of geometry or music. We have a comprehensive theory of chromatic scale of colours, namly the visible light spectrum, but to compose clours in a meaningfull way is stil an art itself. This webpage follows an engineer's approach to design beauty by taking inspiration from nature. When design logic is directly available to the senses, which is the case in constructions like sailing crafts, the real beauty is immidiately seen by both expert and layman eye. Marine blue and yellow are symbolic and traditional, while the rest is taken from Greenland iceberg. If you'd asked me - the colour of the sea is mostly green or grey - just like green or blue-grey eyes. Ice is often much closer to tuquoise than blue. As a matter of fact, the sea can be every colour, but the rule of the composition is there is only one range of colours at once and the propoprtions of particular colours are true only once a while. Therefore one cannot take one colour from the morning sun's reflection on the water, another from the full-moon sky on the high sea, and another from sun-bathed sandy beach into the single composition to use it as 'the colours of the sea' Great colour compositions are always the art of camouflage, both in colours itself, the proportions of the spots and their correspondence, including reflections, shades and shapes.
