Results from the study show the average IQ of blondes was slightly higher than those with other hair colors. Blonde-haired women had an average IQ of 103.2, compared to 102.7 for those with brown hair, 101.2 for those with red hair and 100.5 for those with black hair.
Among white women, blondes had the highest mean IQ at 103.2 points, followed by women with brown hair (102.7), red hair (101.2), and black hair (100.5).
The study found that the average IQ of blondes was actually slightly higher than those with other hair colors, but that finding isn't statistically significant, said Zagorsky, who works in the university's Center for Human Resource Research (CHRR).
People with brunette hair are the most attractive.
By presenting pictures of the same woman with different dye hair colors, the researchers found that out of the population analyzed, 67 percent of men preferred the woman with brunette hair and 71 percent of women chose the man with brunette hair.
#1 Most Popular Hair Colour – Black Hair
In fact, around 75 to 85 percent of the people in the world have some shade of black hair.
Only 2 percent of the world's population has naturally blond hair. If you narrow your sample to white people in the United States, that percentage goes up, but only to 5 percent.
True blonde is also a rare hair color, and the Daily Mail reports that only 12.7 percent of women have pure blonde hair, and only 9.9 percent of men do. Surprisingly, many of the genetic differences identified by the researchers correlated with factors other than pigmentation like hair texture and growth.
Naturally-occurring blond hair is primarily found in people living in or descended from people who lived in the northern half of Europe, and may have evolved alongside the development of light skin that enables more efficient synthesis of vitamin D, due to northern Europe's lower levels of sunlight.
Red is the rarest hair color, according to Dr. Kaplan, and that's because so few MC1R variants are associated with the shade. “Only three variants are associated with red hair,” she says. “If a person has two of these three variants, they almost certainly have red hair.

Brown hair is the second most common human hair color, after black. Brown hair is characterized by higher levels of eumelanin and lower levels of pheomelanin. Of the two types of eumelanin (black and brown), brown-haired people have brown eumelanin; they also usually have medium-thick strands of hair.
In concurrence with both earlier studies, the results of this study indicated red hair as the least preferred hair color. In the Likert scale positive characteristic evaluation, as well as in the survey questions, brunettes were given the highest ratings of all three categories.
Essentially, anything that isn't blonde, brown, black, or gray is a no-go.
Caramel, honey, gold, copper, and strawberry give a healthy brightness that makes us look and feel younger. (Framing your face with lighter shades draws the eye away from any complexion concerns, as well.)
Blue: Blue is the color of trust, confidence, and intelligence. Blue encourages intellectual activity, reasoning and logical thinking, and acquires lessons faster. That is the color of intellect.
A recent survey conducted by CyberPulse, a division of Impulse Research Corporation in Los Angeles uncovered this colorful research. Intelligence was the number one trait associated with brown, the most common eye color in the U.S., by 34 percent of respondents.

Green is the color of ingenuity and learning. "Geniuses pick green," said Robert DeNiro in Meet The Parents. Scientists have found that a room painted green can actually improve a child's learning speed and retention.
Blue: Intellectual
Blue is a soothing color, helping calm the mind and aid concentration. It's no wonder then that blue is a popular color to use in office spaces. It enhances wakefulness and supports clear communication.
Apparently blue is the most popular color in the world. It is associated with competence, intelligence and trustworthiness.
Green is considered by some to be the actual rarest eye color in the world, though others would say it's been dethroned by red, violet, and grey eyes. Green eyes don't possess a lot of melanin, which creates a Rayleigh scattering effect: Light gets reflected and scattered by the eyes instead of absorbed by pigment.
We found that green is the most popular lens colour, with brown coming in a close second, despite it being one of the most common eye colours. Although blue and hazel are seen as the most attractive eye colours for men and women they are surprisingly the least popular.
Just as with blonde hair, red hair requires a little extra tender love and care. Hack admits that red hair is his favorite to color, but that she's noticed many women don't realize the extent of after-care that's needed. “Red is the hardest color to keep lustrous and the hardest color to remove,” she adds.
Essentially, green eyes are unique. Most common in Western, Northern, and Central Europe, green eyes often point to German or Celtic ancestry. Currently, they can be found most often in Iceland, the Netherlands, Scotland, Britain, and Scandinavia.
As the population grows and people have babies, the genes for less melanin will become more common. That makes the link between lighter eyes, hair, and skin tighter. So that's why you see people with blond hair typically have blue eyes!
