Skin Pigment Numbers

Because "black", "white", "yellow", "brown", and "red" are inadequate
  [vote for,

There are two varieties of melanin that are responsible for most human skin color. Pheomelanin is a yellow or reddish pigment (depending on concentration), and eumelanin is a deep brown pigment. Most humans have both, but usually one predominates very-much more than the other.

Now consider the average "black" American, and compare that person to a native of the African equatorial region. It is *laughable* to call that American "black"! Not to mention that the African's skin color isn't really black, either; it is more like a super-dark chocolate.

You may now understand why a better way of describing human skin pigmentation is needed. Here we shall suggest a pair of numbers, from 0 to 100+, in which 100 is defined as the normal maximum level of one of the two pigments. (There is an illness called "hyperpigmentation" in which someone could have a number greater than 100, but that is not *normal*.)

In alphabetical order, eumelanin precedes pheomelanin. So let the first number represent the amount of eumelanin in someone's skin, and the second number represent the amount of pheomelanin. We could write down the values as, for example, 15|5 ("ASCII vertical bar" separating them). An albino would have values of 0|0, of course, and if that first example human got a sun-tan, the numbers might change to become 20|6.

As a consequence of most humans having a predominance of one of the two pigments, most humans would have a quite-low value for one of the two numbers --"red" humans, for example, might only have a 2 for the first number.

Some folks will now claim that such a system, while accurately describing skin colorations, will promote prejudice. "Our private club excludes anyone whose numbers fall outside the range of ...!" Well, maybe. My only comment about that is, "Where in the HalfBakery is a "Prejudice" category???" (where this Idea would properly belong)

       Somewhat baked in pre-1994 South Africa, eg the Pencil Test and all that kind of stuff..

       Why not just use Pantone? This is a wider colour palette and would allow for when aliens colonise the Earth and wipe out all humans.

       Munsell system would be better.

       I wonder if generic engine-hearing could give rise to at-will colouring, via variable structural colouration and schemochromes — especially if we all tried harder to sprout reflectin proteins in chromatophore cells in our skin. Of course, the make-up industries would collapse (as would the bikini industry).

       Racial classifications beeb story   

       "In 1984, for example:   

       518 Coloured people were defined as White, 2 whites were called Chinese, 1 white was reclassified Indian, 1 white became Coloured and 89 Coloured people became African"   

       You still quite sure you want go down this path?
