Mapping, colormap, eigenvector

Can anyone help me!!!

I want to plot countries including their borders in Europe and then set the color of each country according to a number. Currently I am able to generate a map consisting of about 50 country shape files. Now, I want to change the Facecolor of each shape file according to the value of an eigenvector.

My problem is, how to generate or calculate a colormap, so each number eigenvector correspond to a color (like the colormap jet). Large values would correspond to a darker red, small values to a darker blue etc... How can I do this ?
