Human hair color
Hair color is the pigmentation of hair follicles due to two types of melanin: eumelanin and pheomelanin. Generally, if more eumelanin is present, the color of the hair is darker; if less eumelanin is present, the hair is lighter. The darker a person's natural hair color is, the more individual hair follicles they have on their scalp. Levels of melanin can vary over time causing a person's hair color to change, and it is possible to have hair follicles of more than one color on the same person. Particular hair colors are associated with ethnic groups. Gray or white hair is associated with age. The Fischer–Saller scale, named after Eugen Fischer and , is used in physical anthropology and medicine to determine the shades of hair color.
Blond
Blond (male), blonde (female), or fair hair, is a hair color characterized by low levels of the dark pigment eumelanin. The resultant visible hue depends on various factors, but always has some sort of yellowish color. The color can be from the very pale blond (caused by a patchy, scarce distribution of pigment) to reddish "strawberry" blond or golden-brownish ("sandy") blond colors (the latter with more eumelanin). On the Fischer–Saller scale, blond color ranges from A (light blond) to O (dark blond). The word "blond" is first documented in English in 1481 and derives from Old French "blund, blont", meaning "a colour midway between golden and light chestnut".
Brown hair
Brown hair is the second most common human hair color, after black hair. It varies from light brown to almost black hair. It is characterized by higher levels of the dark pigment eumelanin and lower levels of the pale pigment pheomelanin. Its strands are thicker than those of fair hair but not as much as those of red hair. People with brown hair are often referred to as brunette, which in French is the feminine form of "brunet," the diminutive of "brun" (brown, brown-haired or dark-haired). Brown hair is common among populations in the Western world, especially among those from Central Europe, Southeastern Europe, Eastern Europe, Southern Europe, Southern Cone, the United States, and also some populations in the Greater Middle East where it transitions smoothly into black hair.
Red hair
Red hair (or ginger hair) occurs naturally in 1–2% of the human population. It occurs more frequently (2–6%) in people of northern or western European ancestry, and less frequently in other populations. Red hair appears most commonly in people with two copies of a recessive allele on chromosome 16 which produces an altered version of the MC1R protein. Red hair varies in hues from a deep burgundy or bright copper (reddish-brown or auburn) through to burnt orange or red-orange and strawberry blond. It is characterized by high levels of the reddish pigment pheomelanin and relatively low levels of the dark pigment eumelanin.
Melanin
Melanin (; from "melas", "black, dark") is a broad term for a group of natural pigments found in most organisms. Melanin is produced by the oxidation of the amino acid tyrosine, followed by polymerization. The melanin pigments are produced in a specialized group of cells known as melanocytes. There are three basic types of melanin: eumelanin, pheomelanin, and neuromelanin. The most common type is eumelanin, of which there are two types—brown eumelanin and black eumelanin. Pheomelanin is a cysteine that contains red polymer of benzothiazine units largely responsible for red hair, among other pigmentation.
Equine coat color genetics
Equine coat color genetics determine a horse's coat color. There are many different coat colors possible, but all colors are produced by the action of only a few genes. The combination of the extension and agouti loci determine the base coat of a horse.Bay is the original "wild type" color of horses. Ancient remains of horses were tested to be of bay base coat color. The Dun test was not available at the time, but those horses were also dun. (EE AA DD)  Red horses were created with a modification of the extension locus. Dominant extension mutated into a recessive form. When the horse is homozygous for recessive extension (or ee), the horse's base coat will be red.
Dark skin
Dark skin is a naturally occurring human skin color that is rich in eumelanin pigments and having a dark color. People with relatively dark skin are referred to as brown, and those with very dark skin are often referred to as black, although this usage can be ambiguous in some countries where it is also used to specifically refer to different ethnic groups or populations. The evolution of dark skin is believed to have begun around 1.2 million years ago, in light-skinned early hominid species after they moved from the equatorial rainforest to the sunny savannas. In the heat of the savannas, better cooling mechanisms were required, which were achieved through the loss of body hair and development of more efficient perspiration.

Labrador Retriever coat colour genetics
The genetic basis of coat colour in the Labrador Retriever (a highly popular breed of dog) has been studied in detail, and found to depend on several distinct genes. The interplay between these genes is broadly used as an example of epistasis. Labrador Retrievers are a popular breed of dog in many countries. There are three recognised colours, black, chocolate, and yellow, that result from the interplay among genes that direct production and expression of two pigments, eumelanin and pheomelanin, in the fur and skin of the dog. The recognized colours are due to two genes, while a third gene affects the range of colouration observed within the yellow Labrador.

Brown
Brown is a composite color. In the CMYK color model used in printing or painting, brown is made by combining red, black, and yellow, or red, yellow, and blue. In the RGB color model used to project colors onto television screens and computer monitors, brown is made by combining red and green, in specific proportions. The brown color is seen widely in nature, in wood, soil, human hair color, eye color and skin pigmentation. Brown is the color of dark wood or rich soil. According to public opinion surveys in Europe and the United States, brown is the least favorite color of the public; the color is most often associated with plainness, the rustic, feces, and poverty.

So I suppose that means that brunette hair has lots of Eumelanin.

Correct! the lack of Eumelanin results in a yellowish color.

Amelanism
Amelanism (also known as amelanosis) is a pigmentation abnormality characterized by the lack of pigments called melanins, commonly associated with a genetic loss of tyrosinase function. Amelanism can affect fish, amphibians, reptiles, birds, and mammals including humans. The appearance of an amelanistic animal depends on the remaining non-melanin pigments. The opposite of amelanism is melanism, a higher percentage of melanin. A similar condition, albinism, is a hereditary condition characterised in animals by the absence of pigment in the eyes, skin, hair, scales, feathers or cuticle. This results in an all white animal, usually with pink or red eyes.

Albinism in biology
Albinism in biology is the "Congenital absence of any pigmentation or coloration in a person, animal or plant, resulting in white hair and pink eyes in mammals." Varied use and interpretation of the terms mean that written reports of albinistic animals can be difficult to verify. Albinism can reduce the survivability of an animal; for example, it has been suggested that albino alligators have an average survival span of only 24 hours due to the lack of protection from UV and their lack of camouflage to avoid predators. Albino animals have characteristic pink or red eyes because the lack of pigment in the iris allows the blood vessels of the retina to be visible.

What does that mean for people with red or auburn colored hair?

Some red hair involves Eumelanin but it also involves a different more reddish hair pigment. Some blond people are referred to as strawberry blond.
The color can be from the very pale blond (caused by a patchy, scarce distribution of pigment) to reddish "strawberry" blond or golden-brownish ("sandy") blond colors (the latter with more eumelanin).

List of unidentified murder victims in the United States
Of the thousands of people murdered every year in the United States, some remain unidentified. Many victims are not identified for years or even decades after they were killed—as in the case of Tammy Jo Alexander, who was murdered in 1979 and remained unidentified until 2015. Including both murder victims and those who died of other causes, about 40,000 bodies remain unidentified in the United States. The body of a white female aged thirty-four to thirty-eight was found in Slaughter Creek, near the Sipsey River in Romulus, Tuscaloosa County, Alabama on April 18, 1982. The victim had been beaten, strangled and sexually assaulted.

Human overpopulation
Human overpopulation (or population overshoot) occurs when the ecological footprint of a human population in a specific geographical location exceeds the carrying capacity of the place occupied by that group. Overpopulation can further be viewed, in a long term perspective, as existing if a population cannot be maintained given the rapid depletion of non-renewable resources or given the degradation of the capacity of the environment to give support to the population. Changes in lifestyle could reverse overpopulated status without a large population reduction. The term "human overpopulation" refers to the relationship between the entire human population and its environment: the Earth, or to smaller geographical areas such as countries.

World population
In demographics, the world population is the total number of humans currently living. The world population was estimated to have reached 7.6 billion as of December 2017 . The United Nations estimates it will further increase to 11.8 billion by the year 2100. World population has experienced continuous growth since the end of the Great Famine of 1315–17 and the Black Death in 1350, when it was near 370 million. The highest population growth rates – global population increases above 1.8% per year – occurred between 1955 and 1975, peaking to 2.06% between 1965 and 1970. The growth rate has declined to 1.18% between 2010 and 2015 and is projected to decline to 0.13% by the year 2100.
Demographics of the world
Demographics of the world include population density, ethnicity, education level, health measures, economic status, religious affiliations and other aspects of the human population of the planet Earth. The overall total population of the world is approximately 7.47 billion, as of July 2017. Its overall population density is 50 people per km² (129.28 per sq. mile), excluding Antarctica. Nearly two-thirds of the population lives in Asia and is predominantly urban and suburban, with more than 2.5 billion in the countries of China and India combined. The World's fairly low literacy rate (83.7%) is attributable to impoverished regions.
Introduction to genetics
Genetics is the study of genes—what they are, what they do, and how they work. Genes inside the nucleus of a cell are strung together in such a way that the sequence carries information: that information determines how living organisms inherit various features (phenotypic traits). For example, offspring produced by sexual reproduction usually look similar to each of their parents because they have inherited some of each of their parents' genes. Genetics identifies which features are inherited, and explains how these features pass from generation to generation. In addition to inheritance, genetics studies how genes are turned on and off to control what substances are made in a cell—gene expression; and how a cell divides—mitosis or meiosis.
Economic history of Mexico
Mexico's economic history has been characterized since the colonial era by resource extraction, agriculture, and a relatively underdeveloped industrial sector. Economic elites in the colonial period were predominantly Spanish born, active as transatlantic merchants and silver mine owners and diversifying their investments with the landed estates. The largest sector of the population was indigenous subsistence farmers, who lived mainly in the center and south. New Spain was envisioned by the Spanish crown as a supplier of wealth to Iberia, which huge silver mines accomplished. A colonial economy to supply foodstuffs and products from ranching as well as a domestic textile industry meant that the economy supplied much of its own needs.
