In Flash S04E18, when the Thinker is cuffed by Ralph Dibny using metahuman dampener cuffs, he says:
Before you cuff a meta, make sure the light is the right color.
He was able to break free from the cuffs after saying this.Also, he had the power of all the metas except Dibny at that point so did he use some metas ability to uncuff himself.What color is DeVoe referring here? What is the context of this line here?
Basically, I want to ask that what exactly he did to free himself.
