No!
Light pink to cherry red is what auto trans fluid looks when new. A sign of coolant in the trans oil would look like strawberry milk. And brown doesnt always mean burnt, could just be worn/old fluid. But burnt trans fluid does have a distinctive smell to it. When I was going to school to be a mechanic many of years ago we where always taught to never judge condition of tranny fluid by the looks of it unless it was a strawberry milk look thats obvisous. We where always taught to go by smell.
I will agree with a dark grey to black color that means something inside the trans was coming apart.
