Hi, Olalla, 

    I suspect you're using a version of Mathematica prior to 6, because 6 uses 
a default ColorFunction which colors the levels differently for the minimum 
and maximum. In previous versions (at least in 5), the default color function 
was "Hue", which has the dubious advantage of being periodic in the visible 
color range.

   You can change the ColorFunction for your plot by trying something like:

ListContourPlot[<your list>, ColorFunction -> (Hue[0.73*(1 - #)] &)]
