Color of tranny fluid when changed

I changed my tranny fluid on my 06 2.3 auto a few months back @ about 20k. Replaced it with Mobil 1. My fluid was a dark brown to almost black color it,did not smell burnt though. I have not had any problems with my transmission. Was this a problem, or normal for the Mazda Fluid? The Mobil 1 has remained a nice bright red since the change(been 5k). For those of you that have done your own change, what has been your experience? If you could, post mileage at change.
Thanks..

i just replaced the MTX tranny fluid at 31K...fluid came out dark brown/blackish. i was surprised cuz when i changed the tranny fluid on my 99 honda civic at 20K it was almost as good as new.

definitely not going to follow the maintenance sched in the mazda3 owners manual.

i'll be replacing the ATX fluid in my wife's car this week. her car has 27K...i'll see what color fluid comes out...
