The 'red' radical. A compound of 大 (large) over 火 (fire) — a person standing in flame, the deep red of fire-color in pre-Qin texts. Indexes very few characters (赦 'pardon', 赫 'awe-inspiring', 赭 'reddish brown'). More important as the literary alternative to 红 and as a culturally loaded color associated with the south, ritual, and revolution.
