Altered Maps XIV: Cartographical Consistency

Ah, I thought it was going to be something about homosexuality. Whenever Greece and India get mentioned in the same sentence, for some reason my mind automatically jumps to ancient times.

Here's a world map of blonde hair.

What's with the splotch near the Canadian border?
 
I have some doubts about the reliability of that map, at least when it comes to some regions.

For example according to that map even southern Germany has over 50% blondes and northern half (or more than half?) has over 65% blondes.

This data from German website about hair colours in Germany contradicts that map:

http://www.haar-und-psychologie.de/haarfarben/haarfarben_statistik_deutschland.html

According to this chart three blonde colours (light, medium and dark blonde):

Northern Germany - 50,9% males / 55,2% females (average 53,05%)
Central Germany - 47,2% males / 49,6% females (average 48,4%)
Southern Germany - 45,6% males / 45,2% females (average 45,4%)

However, "dark blonde" ("dunkelblond") is often also being classified as "light brown" or "medium brown".

These differences in naming of colours are caused by fact that there exist several different scales for hair colours.

Probably one of the best scales is the Fischer-Saller Scale where "blonde" are colours (shades) from A to O.

And here are maps for hair and eye colours in Europe from Eupedia:

Also in case of Melanesia I'm quite sure that they have a bigger percent of blondes than just 0% - 1%, as that map indicates.

Google "blonde Melanesians" (BTW - some East Asians also have naturally blonde hair, but at very low frequencies).

So that map is indeed "altered", because it does not reflect the reality too accurately.

This should probably go to "Daily graphs and charts", but since discussion about phenotypes / pigmentation started, so let's post it here:

Explanation:

In medicine, the classification of skin color has stemmed primarily from the need to quickly and reliably evaluate the risk of skin cancer in light-skinned patients, in the setting of a doctor's office. Because lightly pigmented people differ in their ability to tan and are not equally susceptible to sunburn and skin cancer risk, the method of skin phototyping, developed in 1975, helps physicians accurely predict a person's reaction to moderate sun exposure. According to this classification system, there are six skin phototypes: three are referred to as "melanocompromised" (phototypes I-III) and three considered "melanocompetent" (phototypes IV-VI). The definition of sun exposure in this system is thirty minutes of unprotected exposure without sunscreen at peak (summer) UVR levels.

Domen, what is called light or dark hair is usually decided by comparison. Some hair colours in Northern Europe would classify as 'brown' or 'dark' while in other places they'd be 'dark blonde' at best.
