isn't turkey meatloaf suppose to be brown even if it has ketchup.

I'm sure it won't be as brown as when you use ground beef for meatloaf. Probably depends on the ratio of dark turkey meat to white turkey meat.

thank you very much.

I had fun reading this about WHY meat does or does not turn brown when it's cooked! It's all about something called myoglobin...
