Seven...Red, Orange, Yellow, Green, Blue, Indigo, and Violet. Red, green, and Blue is more honest, the other four are a mix..

I had never seen a complete end to end rainbow before moving to New Mexico. I came into work one morning coffee in hand, and a native New Mexican said "What are you smiling about? You look like a coyote raiding a hen house." I said I doubt you'd understand... but I just saw a complete rainbow, the whole thing end to end, and all of the colors. He said yeah, big deal... wait till you see a double, then tell me you saw sumthin. I have since seen a double rainbow.... awesome!

I love colors!
If I could have I would have gone to college to be a colorist

I saw a huge rainbow a few months ago, just humongus!
Very nice, everybody on the street stopped to stare, people in cars too!

cool wag you saw a double rainbow? I think I have seen one

Colorist
From Wikipedia, the free encyclopedia
Not to be confused with Hair colorist.
For motion picture coloring, see color grading and color suite.
For styles of painting, see Colourist painting, Scottish Colourists, and Color Field.

In comics, a colorist is responsible for adding color to black-and-white line art. For most of the 20th century this was done using brushes and dyes which were then used as guides to produce the printing plates. Since the late 20th century it is most often done using digital media, with printing separations produced electronically.

Colorists may work directly for comics publishers (either as employees or freelancers), or they may work for coloring studios which offer their services to publishers. American Color, Olyoptics, and Digital Chameleon are companies notable in this field within the comic strip industry.

They always used to teach ROY G BIV to help kids remember the colors of the rainbow - anyone know if they still do that?

From good ol' Wikipedia:

A rainbow spans a continuous spectrum of colours—there are no "bands." The apparent discreteness is an artifact of the photopigments in the human eye and of the neural processing of our photoreceptor outputs in the brain. Because the peak response of human colour receptors varies from person to person, different individuals will see slightly different colours, and persons with colour blindness will see a smaller set of colours. However, the seven colours listed below are thought to be representative of how humans everywhere, with normal colour vision, see the rainbow. The final colour in the rainbow is violet, not purple.

Newton originally (1672) named only five primary colours: red, yellow, green, blue and violet. Later he included orange and indigo, giving seven colours by analogy to the number of notes in a musical scale.

Red Orange Yellow Green Blue Indigo Violet

I saw some double rainbows in NM too. BeautifulI, I saw pink, yellow, purple, green and blue. It was so great it was after a beautiful rain and I was having lunch at Souper Salad and we were sitting next to the window and when we finished we went out and walked and saw all it's beauty.

Hey Bunch.... tell them about the sunsets!

:)

Do you know HOW a rainbow ORIGINATES? It is NOT from the rain..

It seems that our beautiful earth's sky IS rainbow colored. It already IS a rainbow effect. It is only when the rain stops and there is a haze of moisture in the rainbow - colored sky that there it a reflection of its true colors caused by the moisture gathered in the air.

I learned this in one of the many science books I have bought for my young grand-daughters.

All good info on here!

Still wish I was a colorist-GEE I wish I had the focus to do this
also read that colorists work for interior decorators, cosmetic companies, product colors, like they use certain colors on products to make you want to buy them

Sunsets are awesome! all pink orange, yellow, purple, indigos, just too cool for words.

Also this I found too-

olor Psychology

Do you feel anxious in a yellow room? Does the color blue make you feel calm and relaxed? Artists and interior designers have long understood how color can dramatically affect moods, feelings and emotions. It is a powerful communication tool and can be used to signal action, influence mood and cause physiological reactions. Certain colors can raise blood pressure, increase metabolism or cause eyestrain.

Of course, your feelings about color can also be deeply personal and are often rooted in your own experience or culture. For example, while the color white is used in many Western countries to represent purity and innocence, it is seen as a symbol of mourning in many Eastern countries.

Why is color such a powerful force in our lives? What effects can it have on our bodies and minds? Continue reading to further explore the history of color including how it's used, the effects it may have and some of the most recent research on color psychology.
What Is Color?

In 1666, English scientist Sir Isaac Newton discovered that when pure white light passes through a prism, it separates into all of the visible colors. Newton also found that each color is made up of a single wavelength and cannot be separated any further into other colors.

Further experiments demonstrated that light could be combined to form other colors. For example, red light mixed with yellow light creates an orange color. Some colors, such as yellow and purple, cancel each other out when mixed and result in a white light.

If you have ever painted, you have probably noticed how certain colors can be mixed to create other colors. Marion Boddy-Evans, About.com's Guide to Painting, has an excellent overview of color theory basics including how different colors can be mixed.
Color Psychology - The Psychological Effects of Color

While perceptions of color are somewhat subjective, there are some color effects that have universal meaning. Colors in the red area of the color spectrum are known as warm colors and include red, orange and yellow. These warm colors evoke emotions ranging from feelings of warmth and comfort to feelings of anger and hostility.

Colors on the blue side of the spectrum are known as cool colors and include blue, purple and green. These colors are often described as calm, but can also call to mind feelings of sadness or indifference.
Color Psychology as Therapy

Several ancient cultures, including the Egyptians and Chinese, practiced chromotherapy, or using colors to heal. Chromotherapy is sometimes referred to as light therapy or colourology and is still used today as a holistic or alternative treatment.

In this treatment:

Red was used to stimulate the body and mind and to increase circulation.

Yellow was thought to stimulate the nerves and purify the body.

Orange was used to heal the lungs and to increase energy levels.

Blue was believed to soothe illnesses and treat pain.

Indigo shades were thought to alleviate skin problems.

Most psychologists view color therapy with skepticism and point out that the supposed effects of color have been exaggerated. Colors also have different meanings in different cultures. Research has demonstrated in many cases that the mood-altering effects of color may only be temporary. A blue room may initially cause feelings of calm, but the effect dissipates after a short period of time.

Studies have also shown that certain colors can have an impact on performance. Exposing students to the color red prior to an exam has been shown to have a negative impact on test performance. More recently, researchers discovered that the color red causes people to react with greater speed and force, something that might prove useful during athletic activities.

color also has deep meaning in some religious paths, for example for Wiccans black is seen as protective and wear it for that reason while Native Americans find it sinister and rarely don it. in Asian cultures red is seen as joyful and is often the choice of brides =) i woudln't mind that at all since it's my all time favorite color - the color of life i used to think as a child. i have a lot of it in my home even now. (in fact the robe i'm wearing is red...is that tmi?)

and since yins were discussing the rainbow did ya know it's ALWAYS double? you can't always seen the 'second' one but its' there =) i attended weather school while in the air force and it was one of the most amazing things i've ever studied - i didn't fulfill my hope of becoming a meteorologist because i 'washed out' due to an illness but it was a great education! so next time you see a rainbow look and see if you can't find the lighter one next to it.

Thanks, Everybody !!
