From Create Your Own Story
when you get to the sphere you recognize it at Wheatley. he wakes up and begs you get get him free. "please, there is a switch, or a button outside of here. shut it off." he says in a panic.
you look around for a way out and see a hatch above you. you shoot at it and it flies open. The portal hits the ceiling past the hatch so you shoot another portal at the floor and jump through, leaving you ontop of the machine.
you quickly ask him what the off switch looks like.
"its red" he says.
you start to run off looking for it
"WAIT" he yells back. "i think its actually yellow"
you thank him then go back to searching.
"MAYBE BLUE" he yells
