The beauty of nature's colors only becomes fully visible in sunlight, whether it is the splendid miracle of the rainbow or its various different forms in nature; none of the colors is a coincidence - not the green of the leaves, nor the red of blood or the deep black of space. The film gives an overview of the fascinating world of color in all its different manifestations; a journey from inorganic nature to plants, animals and to people. In the light of the sun all colors are contained. How is this possible? In wildlife and nature colors are messages: flowers, for instance, show insects the way to the nectar and thus to the stamens that load them with pollen and animals use colors as bait, as camouflage or to ward off enemies. Why does this communication works? This documentary tries to explain these questions with all new technology and breathtaking images.
