That depends on what coloring model you have chosen. Probably you have selected "color by sign", thus the two colors indicate positive and negative values. Insert the colormap and you will see!

PS: PNG is a much better image format than BMP ;) Smaller filesize and viewable directly in the browser (like JPG), but no loss of quality (unlike JPG, which is designed for photographs, not drawings).
