The .fmp format FWE uses is the older text based format. So its human-readable if you open it in a text editor. Look at the ISO fields assigned to each polygon (ISO in this context refers to the elevation). That should show the elevation (I believe in centimeters). The Brush color is the fill color of that polygon. There will be multiple polygons for each ISO.
You could also make a script that will show the ISO field for a selected polygon. Brush color would be show in the toolbar.
