Colours of the Rainbow

With all the crazy weather we’ve been having lately and the fact that rainbows are definitely a possibility I thought perhaps we’d take the time to look at some facts about rainbows. How’s they’re made and what the colours in the rainbow actually mean.  Just a little something different this week… hope you enjoy.

rainbow is an optical and meteorological phenomenon that causes a spectrum of light to appear in the sky when the sun shines onto droplets of moisture in the earth’s atmosphere. Rainbows caused by sunlight always appear in the section of sky directly opposite the sun.

The rainbow is not located at a specific distance, but comes from any water droplets viewed from a certain angle relative to the Sun’s rays. Thus, a rainbow is not a physical object, and cannot be physically approached. Indeed, it is impossible for an observer to manoeuvre to see any rainbow from water droplets at any angle other than the customary one of 42 degrees from the direction opposite the Sun. Even if an observer sees another observer who seems “under” or “at the end” of a rainbow, the second observer will see a different rainbow further off-yet, at the same angle as seen by the first observer.

Rainbows can be observed whenever there are water drops in the air and sunlight shining from behind at a low altitude angle. The most spectacular rainbow displays happen when half the sky is still dark with raining clouds and the observer is at a spot with clear sky in the direction of the sun. The result is a luminous rainbow that contrasts with the darkened background.

The rainbow effect is also commonly seen near waterfalls or fountains. In addition, the effect can be artificially created by dispersing water droplets into the air during a sunny day.

In a “primary rainbow”, the arc shows red on the outer part, and violet on the inner side. This rainbow is caused by light being refracted while entering a droplet of water, then reflected inside on the back of the droplet and refracted again when leaving it.

In a double rainbow, a second arc is seen outside the primary arc, and has the order of its colours reversed, red facing toward the other one, in both rainbows. This second rainbow is caused by light reflecting twice inside water droplets.


Now with a better understanding of the rainbow let’s take a look at the colours of the rainbow:

Violet is a combination of the colours red and blue. This is the highest and the subtlest specialization of light. This is because it is at the opposite end of the red colour. This colour is viewed as the completion as well as the beginning of the energy vibration. Different shades of violet have varied meanings. A deep purple symbolizes high spiritual attainment and a pale shade symbolizes love for humanity. The shade violet brings about a stabilizing factor to the frenzied shades of red.

The colour indigo means infinity. It also symbolizes wisdom and self-mastery. The indigo colour is known to be the bridge between the finite and the infinite.

Blue is known as the colour of divinity. This is the colour of the open skies and the oceans. Using the colour blue in our daily lives is said to bring about a peace and understanding. This colour also helps to soothe and relax.

The colour green is formed with the merging of yellow and blue. Therefore, this is located in the center of the spectrum. The colour green, symbolizes harmony, balance, growth and good health.

The colour yellow is vibrant in itself being close to the colour of the sun. This is known to be full of energy. Yellow also means something bright and happy and the usage of this colour is known to bring about a proper clarity of thought in a persons mind and also improve the decision-making skills.

The colour, orange is a combination of red and yellow. This is not as fiery as red and but symbolizes a lot of energy and wisdom as well. Although dynamic, the colour orange is more thoughtful and controlled. This colour can increase the creativity of the person and bring about equilibrium in life.

This is the colour of energy and enthusiasm. This is also the colour with the longest wavelength. Red symbolizes passion, energy, vibrancy and success.

Hope you enjoyed this weeks blog… as we said, just a little something different.

Enjoy your weekend!
