A show in my city :O....

Rainbow or rainbow is an optical and meteorological phenomenon that consists of the appearance in the sky of an arc (sometimes two) of multicolored light, originated by the decomposition of sunlight in the visible spectrum, which is produced by refraction , When the rays of the sun cross small droplets of water contained in the terrestrial atmosphere. It is an arc composed of concentric arcs of colors, with no solution of continuity between them, with the red towards the outside and the violet towards the interior.

Colors of the visible spectrum.

Less frequent is the double rainbow, which includes a second thinner arc with inverted colors, ie red inward and violet outward. Although rainbow is a continuous gradient of spectral colors, it is considered that these can be defined in seven fundamental colors: red, orange, yellow, green, cyan, blue and violet, which are equivalent to those mentioned by the scientist Isaac Newton in 1704 (Red-orange-yellow-green-blue-indigo-violet, respectively). In the RGB system, which is a light color model, it corresponds to three primary colors, two secondary colors and two tertiary colors.
