The two phenomena may be told apart by their difference in colour profile: supernumerary bands consist of subdued pastel hues (mainly pink, purple and green), while the twinned rainbow shows the same spectrum as a regular rainbow. The cause of a twinned rainbow is believed to be the combination of different sizes of water drops falling from the ...
The river is commonly called the "River of Five Colors" or the "Liquid Rainbow," and is noted for its striking colors. [1] [2] The bed of the river from the end of July through November is variously colored yellow, green, blue, black, and especially red, the last caused by Rhyncholacis clavigera (syn. Macarenia clavigera) plants on the riverbed ...
Iridescence is caused by wave interference of light in microstructures or thin films. Examples of iridescence include soap bubbles, feathers, butterfly wings and seashell nacre, and minerals such as opal. Pearlescence is a related effect where some or most of the reflected light is white. The term pearlescent is used to describe certain paint ...
The conventional gradient colors of the rainbow symbol. ROYGBIV is an acronym for the sequence of hues commonly described as making up a rainbow: red, orange, yellow, green, blue, indigo, and violet. When making an artificial rainbow, glass prism is used, but the colors of "ROY-G-BIV" are
The colors of the sun dog finally merge into the white of the parhelic circle (if the latter is visible). [6] The same plate-shaped ice crystals that cause sun dogs are also responsible for the colorful circumzenithal arc, meaning that these two types of halo tend to co-occur. [7]
A rainbow spans a continuous spectrum of colors; the distinct bands (including the number of bands) are an artifact of human color vision, and no banding of any type is seen in a black-and-white photograph of a rainbow (only a smooth gradation of intensity to a maxima, then fading to a minima at the other side of the arc).
Articles relating to the rainbow, a meteorological phenomenon that is caused by reflection, refraction and dispersion of light in water droplets resulting in a spectrum of light appearing in the sky. It takes the form of a multicoloured circular arc. Rainbows caused by sunlight always appear in the section of sky directly opposite the Sun.
