Collei's hair is styled by a large hairpin resembling a flower with a black ribbon. She wears an earring with a large gem on her left ear. She has tousled green hair and pink eyes. Collei is about 5’1. Collei's outfit consists of a green shawl with gold tassels worn over a brown dress that exposes her upper back, has detached sleeves, and a small black ribbon on the back with gold trinkets, black gloves that cover only her palms and leave her fingers exposed. Around her waist is a belt; her Dendro Vision, which has two long orange ribbons attached, hangs from the belt on her left side, golden brown open-toe stockings one leg at her thigh and the other reaching just above her knee, a golden band on her left thigh, black heeled boots with a fur trim that leave her toes exposed, and a long yellow scarf with gold details. Collei is cheerful, optimistic, positive, and bright. But also introverted, reserved, and a bit shy. She is a skilled forest ranger, working under her mentor, Tighnari!
