Sigh.

You don't even know what the theorem says, as the paragraph above shows.

The theorem states: GIVEN a planar map, in which countries are connected, it is possible to produce a *FULL* coloring using no more than four colors in which no two countries that share a border (which is more than isolated points) are assigned the same color.

It does not deal with "partial colorings".

Then you are not talking about the Four Color Map theorem. You are talking about something else.

And if you are talking about this something else, then what you are doing is completely useless and irrelevant, since a pie chart with n "slices" provides you with a map that requires at least n colors, for any positive integer n and all your ruminations are useless and irrelevant.

Clear now, or will you again ignore it and repeat the same ignorant nosense in the hope that repetition will stand in for information?
