Ink has a brown cape that wraps around his neck, a tan-colored shirt, a brown vest with straps, brown shorts, a jacket around his waists, his paintbrush, and finally a strap featuring all of his emotion vials, including the white vial XGaster told him to keep. When he is in his emotionless form, he appears to be made of dust, like his attacks. When we see him in 0.4, paintbrushes are tucked between his fingers, presumably the source of the bones he hits Error with.
