I completed the level by turning him to gold though I was trying to get the achievement hence the colour change. I was told before that you could get him to change colour even if he was on your team. Yeah I just maxed out ember spirits and quickly dropped him in a torture chamber in execution mode to convert him. I did manage to get him to change colours by having him non converted and killing him repeatedly though.
