Map Coloring                                                                                                        Solutions

This challenge deals with map coloring.  You need to use no more than 4 colors (blue, red, green, or yellow) to color six European countries: Belgium, Denmark, France, Germany, Luxembourg, and the Netherlands in such a way that no neighboring countries use the same color. Click on the map to enlarge it and to see which countries have common borders. Please submit your solution using your favorite BR&DM tool or no tools at all.
