Now I read that in the upper northern part of china, you can start finding people with blondish hair and some with natural green and blue eyes. That however may be the result of generations of mixing with caucasians and asian people (bordering russia and neighboring arab coutnries). In fact it is used to believe that there are three major types of people, caucasiod, mongoloid and negroid types. There are a lot of sub groups within each group but those are the main groups.
You don't have to be mix to be born with blue or green eyes, and to have light color hair like blonde or red hair.
Blue eyes
Blue eyes are relatively common throughout Europe, especially in
Northern Europe, including the northern
Baltics and in
East Central Europe.
Among human phenotypes, blue eyes are a relatively rare eye color. They are found mainly in people of
northern European and
eastern European descent, and to a lesser extent, in people of
southern Europe[

Central Asia, most commonly in people who live at higher elevations.
South Asians may also have blue eyes, but this is uncommon, except amongst
Pathans and
Parsis and people in Pakistan, and also in India. For example, blue eyes are most common in Punjab and Kashmir, with fewer numbers in Gujarat and Rajasthan.
Finland has the highest percentage of blue-eyed people.
Ireland and
Great Britain also have high percentages of blue eyes. Although very rare, there are instances of blue eyes occurring in people of
African descent.[

Blue is the color of the indole monomer that when polymerised forms melanin[
citation needed]. If both alleles for brown eyes (a polymerase gene) are absent or damaged, the blue color remains. Hence blue eye color is a
recessive trait.
In the mid-
20th century after the dawn of color films, blue eyes were considered very desirable in those aspiring to be
Hollywood actors and actresses. This became less true toward the latter half of that century.
A 2002 study found the prevalence of blue eye color among non-Hispanic whites in the United States to be 57.4% for those born between 1899 and 1905 compared to 33.8% for those born between 1936 and 1951
[4]. This seems to have been caused by the large wave of Italian, Jewish, and other Eastern and Southern European immigration between 1890 and 1914. The largest groups (Irish, German, and English) all have about 40% blue eyes, but the proportion of whites born in groups other than these had shifted from predominately Scottish, Scandinavian and Dutch around 1900 (who have a majority of blue-eyed people) to largely Italian (8% blue eyes), Polish (32% blue), and French Canadian (30% blue), among others

Green eyes
Green eyes
Green eyes are rarer than brown, black, hazel, blue and gray eyes. Green eyes are most often found in people of
Celtic,
Germanic, and
Slavic descent.
Hungarians have the highest percentage of green eyes of any population, close to 20%.[
citation needed] Green eyes are also found, though in far lower proportions, among other
Caucasian populations in the
Middle East and
South Asia. They are so common among
Pashtuns that in Pakistan, Pashtuns are often called "Hare Ankheian Vaale": the green-eyed people.[
citation needed]. They may also be found in many areas of northern India, especially in Punjab and Kashmir.
One of the most famous photographs ever published by
National Geographic was a close-up of
Sharbat Gula, a
Pashtun girl with startling green eyes, taken in western Afghanistan by
Steve McCurry in
1984. Details of her irises captured by the photograph were used to confirm her identity after she was relocated in
2002.
Blond Hair
Naturally blond hair.
Blond hair is a relatively rare
human phenotype, occurring in 1.7 to 2% of the world population with the majority of natural blondes in
Scandinavia and other parts of
Europe, most notably on the northern part of the continent. Blond hair ranges from nearly white (
platinum blond,
tow-haired) to a dark golden brown. A common stereotype holds that Western
men are known to prefer fair-haired
women to their darker-haired contemporaries and this has caused many women to dye or bleach their hair blond.
Blond hair occurs in peoples of
Europe (especially of non-Latin or Mediterranean heritage), in some areas of South
Asia, and even in the
Middle East. It is genetically associated with lighter
eye color such as blue, green, or light brown and with pale, often freckled, skin tones. 5% of Americans are naturally blond.
Blond hair is also associated with
skin cancer (as
melanoma) and
albinism.
Blondness is a
recessive gene and a popular hoax says that the gene will be dead in 200 years.
[7] It has more
phaeomelanin than
eumelanin but has less than
red hair. Natural blondes have the thinnest strand of hair but have more hair on their heads than others. They have an average of 140,000 hairs.

Red Hair
Naturally red hair
Of those previously mentioned, by far the least common hair color present in the United States is
Red hair, shared by only around three percent of the American population. Red hair which ranges from vivid strawberry shades to deep auburn and burgundy is found in Europeans, especially in the
British Isles and is associated with
Ireland and
Scotland. It is less commonly found in peoples of
Japan and some other areas of the world. It is a
recessive gene and believed to be an uncommon one. It is also found in the Middle East, and appears uncommonly in those of African descent.
Red hair is genetically associated with lighter
eye color, especially green, blue, and light to medium brown and pale, often melanin-less skin. Red hair has the highest amounts of
phaeomelanin and the lowest of
eumelanin. They have the thickest strands of hair and the lowest amounts of strands at 90,000.
