The Iroshitei is responsible for determining the color schemes used throughout an anime production. This includes selecting the base colors for characters, props, and environments, as well as designing how those colors change depending on lighting and mood.

The Iroshitei creates detailed color guides called iroshitei-hyō (色指定表), which are followed by the coloring team during the finishing process. Their choices greatly influence the tone and visual consistency of the anime.

Responsibilities:

• Choose base colors and shadow/highlight variations for each asset.
• Create color charts for use by the Shiage (finishing/coloring) staff.
• Ensure consistency in color usage across cuts and scenes.
• Collaborate closely with the Color Supervisor (Shikisai Sekkei) and the Art Director (Bijutsu Kantoku).
