Here are some examples of preserving the colors in a symbol that were 
changing. The big problem with this approach is that it uses up a lot of 
layers, so you might try using one layer with lots of classes, but I'm 
not sure it that will work.

The bug for this problem is:

I just updated it with this information.

## dummy layer to protect symbol colors from changing
   LAYER
     NAME "color_symbol"
     STATUS DEFAULT
     TYPE point
     TRANSFORM false
     FEATURE
       POINTS
         1 1
       END
     END
     CLASS
       SYMBOL "color_symbol"
       COLOR 0 0 0
     END
   END
## protect other colors
   LAYER
     NAME blue
     STATUS DEFAULT
     TYPE point
     TRANSFORM false
     FEATURE
       POINTS
         1 1
       END
     END
     CLASS
       COLOR 0 0 255
     END
   END
   LAYER
     NAME green
     STATUS DEFAULT
     TYPE point
     TRANSFORM false
     FEATURE
       POINTS
         1 1
       END
     END
     CLASS
       COLOR 8 206 107
     END
   END
