Color or colour (see spelling differences) is the visual perceptual property corresponding in humans to the categories called redblueyellowgreen and others. 
Color derives from the spectrum of light (distribution of light power versus wavelength) interacting in the eye with the spectral sensitivities of the light receptors. Color categories and physical specifications of color are also associated with objects, materials, light sources, etc., based on their physical properties such as light absorption, reflection, or emission spectra. By defining a color space, colors can be identified numerically by their coordinates.
Because perception of color stems from the varying spectral sensitivity of different types of cone cells in the retina to different parts of the spectrum, colors may be defined and quantified by the degree to which they stimulate these cells. 
These physical or physiological quantification of color, however, do not fully explain the psycho physical perception of color appearance.
                                                                                                  The science of color is sometimes called chromaticschromatographycolorimetry, or simply color science. It includes the perception of color by the human eye and brain, the origin of color in materials, color theory in art, and the physics of electromagnetic radiation in the visible range (that is, what we commonly refer to simply as light).
In this post, you can read some amazing facts about colors:
1. Men and women see the color red very differently

While those of us who are estrogen producers tend to see maroon, cardinal, and crimson, men typically just see red. No varying tones, hues, or shades just color-crayon, fire engine red. The explanation is actually quite simple and all falls back on basic DNA. Researchers from Arizona State University found that there is a specific gene that allows us to see and interpret the color red. Women have two X chromosomes, while men only possess one. 

Because the particular red-seeing gene sits on the X chromosome, it only makes sense that women would have a full understanding of the red spectrum, while our counterparts only have half the pieces to the racy red puzzle. Therefore, ladies, if you are one of those gals who just cannot make a decision when picking out a shade of lipstick, don't put so much pressure on yourself. It's really of very little importance. 

02. Silver will save your life

When purchasing that brand new vehicle and finding yourself overwhelmed by the 18-page book of options, your best bet is “ and forever will be  to go with silver. Silver-colored cars are least likely to be involved in an auto accident, since they are most visible on the road and in low light. This, coupled with lower insurance rates and the silver color's ability to maintain a look of cleanliness, manifests itself as a sure win.

03. Pink soothes the nerves

Rowdy prisoners and combative patients? Pink is the palliative color, commonly used to splash the walls in prisons and mental health care facilities to assist in subduing those who are out-of-control. So pink definitely has a useful place and a purpose, other than decorating a prom dress or Barbie's dream house.



04. Bright colors will win you friends

Colors are responsible for 62-90% of our first impressions of one another. That means that if you prefer black and neutrals to violets and oranges, it might be time to add a little color to a bland wardrobe to make a better overall impression. Who knows? It could mean the difference between getting the job and meeting the mate of your dreams, or living alone and waking up next to a beer can pyramid on a Tuesday morning.

05. Blue is the most common favorite color
                                                                
Blue is the most favored color in the world, with purple being a distant second. A whopping forty percent of people worldwide would choose blue as their favorite color in playtime poll booth, with purple-lovers lagging way behind at fourteen percent.

06. Colors can be frightening

Chromophobia (also known as Chromatophobia) is the rare, persistent, irrational fear of colors. Some people who have this disorder will react strongly to certain shades or tones, while others will try to avoid color altogether. Some signs and symptoms are: nausea, dizziness, shortness of breath, feelings of panic, elevated heart rate and blood pressure, anxiety, light headedness, headache, and trembling. 

Effective treatment involves methods and techniques that include systematic desensitization and exposure therapy.

07. Yellow makes you hungry

Yellow and orange are not recommended for use in kitchens, as they are known appetite stimulators. With America's ongoing obesity epidemic, it could possibly be time for Sherwinn Williams to do away with bright citruses that have wrongly adorned kitchen walls for the past five decades. 

Then again  where would our restaurant owners be without those clever little tricks that keep our waistlines wide, but leave us wanting more? I am not normally one for conspiracy theories  but perhaps there is something in it for them if we remain ignorant of yellow's effects?

08. Color is an imaginary friend

Technically, its all in our heads: color does not exist at all. It is something created by our brains as a side-effect, when it desperately tries to make sense of the overwhelming amount of information it receives from the outer world. So, should you ever find yourself in a heated debate over color combinations with someone you are certain has an IQ below your cars maximum speed or is just simply colorblind, keep in mind that it is a pointless argument and you should drop it immediately. You are both wrong.

09. Color wheels are the best thing since the wheel

Invented in 1666 by Sir Isaac Newton, the color wheel is by far the best tool to date to help us comprehend the colors that we see. Once we grasp how the color wheel arranges the primary, secondary, and tertiary colors, we can better understand harmonies, or how and why certain colors complement one another. 

The color wheel is a major concept in any color theory class or course, and is crucial for certain careers, such as interior or graphic design.

10. Ground-up-remains-of-mummy goes splendidly with crimson

"Mummy" was once a color in ancient Egypt. Can you guess where the rich brown color received its somewhat macabre name? You guessed it! From the actual ground-up remains of Egyptian mummies, both human and feline. The Pre-Raphaelite painters of the 19th century considered it one of their favorite colors. The authentic pigment was produced all the way up until the early 20th century, when finally the supply of available mummy remains was exhausted. Though no longer containing the remnants of mummified corpses, the color Mummy Brown can still be found today.
