Thrawn's skin was cool- but very much felt alive. Apparently his own did too, given that Thrawn said nothing about the coolness of his skin, even though Astarion thought that out of the two of them, his own skin was coldest.

He pulled his hand back when he let go, "I'm the vainest of them all, so I can only assume my hands say as much."

He was an adept killer and liked being elbow deep in gore- but he always cleaned himself off well. Moisturized his hands. Used his scented oils. And never really did anything that would leave him with any permanent marks of performing a job or task. He enjoyed having very soft, very flexible hands- all the better to wield his knives and gently pull the gold out of people's pockets.
