Sometimes we see two rainbows at once, what causes this? We have followed the path of a ray of sunlight as it enters and is reflected inside the raindrop. But not all of the energy of the ray escapes the raindrop after it is reflected once. A part of the ray is reflected again and travels along inside the drop to emerge from the drop. The rainbow we normally see is called the primary rainbow and is produced by one internal reflection; the secondary rainbow arises from two internal reflections and the rays exit the drop at an angle of 50 degrees° rather than the 42°degrees for the red primary bow. Blue light emerges at an even larger angle of 53 degrees°. his effect produces a secondary rainbow that has its colors reversed compared to the primary, as illustrated in the drawing, adapted from the Science Universe Series Sight, Light, and Color. \nIt is possible for light to be reflected more than twice within a raindrop, and one can calculate where the higher order rainbows might be seen; but these are never seen in normal circumstances.

A rainbow is created when white light from the sun enters droplets of water in the sky and is refracted. The light is refracted when entering spherical droplets, then it is reflected inside them and refracted again upon leaving. This bends the light, as you would see in a lens.  The red end of the spectrum bends less than the blue, which is why they separate when they come out of the drop.\nWikipedia has a page about rainbows, with some diagrams which may help you understand.\nhttp://en.wikipedia.org/wiki/Rainbow

Shades of purple: magenta, mauve, royal, lilac, violet, plum, lavender, indigo, fuchsia, amethyst, periwinkle, and grape.\n \nThings that are these colors: flowers, kings robes, clothes, cabbage, grapes, plums, ink or paint, an anethyst stone, candles, crayons, a bruise, and a color in the rainbow.

The three primary colors that exist are Red, Green and Blue. By mixing these three colors in different proportions, we can get various colors. \n\nIn website design, the colors of each of the primary colors can have a value between 0 to 255. Using combination of these colors, the webdesigners have to write the hexadecimal equivalent of the combination. You can find the color - hexadecimal conversion charts, and detailed information in the following links :\n\nhttp://science.howstuffworks.com/light6.htm\nhttp://eies.njit.edu/~kevin/rgb.txt.html\nhttp://www.hypersolutions.org/rgb.html\nhttp://www.htmlhelp.com/cgi-bin/color.cgi

The rainbow is a prism that occurs when light travels through water or something that can bend the light to creat the colors that we call the rainbow.

If you are asking about light (beams of) then the answer is white.  A prism separates a beam of light into its component parts, producing a "rainbow".  Natural sunlight near mid-day is considered white light.  Sunlight reflected from a white surface likewise can be refracted into a rainbow spectrum because that surface is reflecting all colors of the spectrum.\n\nIf you are talking about pigments, then the combination of all colors is a dark, muddy mess of indeterminate color.

1. white\n2. blue\n3. red\n\n...but they're all pretty sweet

The sunlight spectrum is made of all colors of the rainbow, and seen as light because all the colors are present at the same time. \n\nWater magnifies the visibility of this light and we are able to see the colors of light distinct and separated into the actual colors of sunlight.

there are three primary colours-blue,red and green.white is a mixture of these colours,black absorbs all the colours,so u can see jus black and all the other colours like yellow etc are mixtures of any two of the primary colours

Blue, Purple, and Pink are the three main colors, although green turns up often too.

Rainbows are made from light reflecting off the small droplets of water in the air, usually after it just rained so it doesn't really travel any differently...

HOW A RAINBOW FORMS:\nWhen light travels from one medium to another, it bends. In other words, it changes direction and moves at different speeds in different mediums. This property of light is called “refraction”. \nWe also know that white light is made up of different colours. Different colors of light have different frequencies. Except in vacuum and air, they travel at different speeds in different mediums.\nIf you were to allow a beam of light to pass through a simple prism, it will bend when it enters the prism, when it leaves the prism it bends again. The different colours of the white light travel with different speeds inside the prism. The slanted surfaces of the prism makes the different colours emerge separately, thus in addition to bending light as a whole, a prism separates white light into its component colors. This splitting of light into its component colours is called dispersion, where prism is a dispersing element.\nThis is exactly what happens when the sun rays hit droplets of water. When the sunlight strikes a raindrop, the light is refracted (bent) because the light is moving from one medium(air) to another( water). Drops of rainwater can disperse light in the same way as a prism.. When the light comes out of the water droplet, the sun's rays (white light)have now been split into their component wavelengths (colors). In this way, each individual raindrop behaves just like a prism, dispersing white sunlight into its seven component colors and a rainbow is formed. \nThe rainbow we see is thus a result of many, many raindrops bending the sun's rays.\n\nWHY U SEE 5 COLORS:\nDont worry much! there are many colors in rainbow but we see only those who are flowing in a great band. i mean which have more thickness! some colors dont have much thickness there, so it becomes tough to see them. we generally see 5 colors where it is said that rainbow have 7 colors. sometimes we see only 3! it depends on rainbow too, and changes from rainbow to another! depends on the sun and the intensity of rain too.\n\nBut to take precautions u can go and see a doctor!
