Yes, When emitting a incredible amount of chakra (Rasengan, Chidori)
It becomes visible to the eye. In the cases of Rock Lee, Naruto, Sasuke this requires control. however,
Setting rock leet as example it takes control to open the gates but once they are open he wasn't controling the chakra that was pouring out of him.
In the kyubi's case it more or less the same, chakra pours out naruto giving him insane strenght and speed. We seen that occasional times.
One thing doesn't add up though, wich kind of proves your point
dark trigger
IF that is our definition of Chakra Control....
