Colors of the rainbow
The interaction that occurs to create the rainbow will produce a spectrum of colors in order Red - Orange - Yellow - Green - Blue - Indigo -Violet (ROY G BIV) with Red occurring on the outside edge of the rainbow to Violet occurring on the inside edge (closest to the center) of the rainbow.
As we have seen there are seven colors in a rainbow VIBGYOR: which are Violet; Indigo; Blue; Green; Yellow; Orange; Red. Lets us know the meaning of each color.
Violet: This is the last or the lowermost color in a rainbow. One can get this color as a combination of red and blue. It is the highest and the subtlest specialization of light, as it is at the opposite end of the color red.
Indigo: This is the second color from the bottom in a rainbow. A deepened version of the color blue would give indigo. The energy of the color blue is multiplied by indigo.
Blue: This is the third color from the bottom of the rainbow. When we think of blue and what we get in mind is oceans and the sky. Blue is termed as the nature's color. Blue is the first primary color that comes in VIBGYOR.
Green: Green is the fourth color from the bottom of a rainbow. This color stands in the middle of the rainbow. The color green is formed when the two colors yellow and blue are combined. Hence, this color is located in the center of the spectrum. This is the second primary color in VIBGYOR.
Yellow: This is the fifth color from the bottom of the rainbow. This color is the combination of Red and Green. This is the first secondary color to be observed in VIBGYOR.
Orange: This is the sixth color from the bottom of the rainbow. The color orange is a combination of red and yellow. This color is often observed as orangish-red in nature during sunrise and sun set.
Red: This is the seventh (or) the top most color in a rainbow. Red is also the color with the longest wavelength. This is one of the three primary colors observed in VIBGYOR.
All these colors belong to the visible region of Electromagnetic spectrum. This spectrum is huge consisting of many regions of which humans can observe a small window of Visible colors in visible region.
