White could be when they are in union. Both recognize that Vermillion is stronger than them and escape. Like Andrew said they both fight each other for control and that's why Neo's eyes constantly switch between brown and pink.

Both brown means Neo's in control, Both pink means the other thing or whatever it is in control, switching means that they are fighting, with Neo losing to the monster inside most of the time. White means that they both agree in unison they cooperate.
