Identifies a man's power by observing him

“Hugo,” I said, remembering the names. “Enzo. Is something wrong?”

They were silent for a minute, scanning the area careful. Enzo held a decently sized bag of books in one hand while his brother paced around the area, making sure nothing was hidden from his sight. After a moment, they locked eyes with one another, nodded, and looked at me.

“Red,” Enzo said, his brother keeping a look out. He offered me the bag and I took it, frowning slightly at him.

“Is that good or bad?” I asked. Generally, red meant the latter, but neither of them seemed nervous.

“Red is good,” He said. “Violet is bad.”

I nodded at him considering before just Observing him, and then nodded again in understanding. They could both see danger in the forms of color—Enzo seeing how dangerous something was and Hugo seeing how much danger they were in. Well, that explained why my Grandmother employed them, at least.
