I'm running out of ideas. Have you tried setting the output format to JPG? Since it's a 24-bit format (only), this might indicate if the problem is in the output stage or in the input/processing stage.

I've tested mapserver 5.0.0. Beta 4 (it's the only v5 I've got compiled) and it gives me a 24 bit color image. What version of Mapserver are you using? Can you send your entire map file?
