The kanji 赤 is a pictograph. The top portion of the character originally depicted a person (大) and the bottom portion represents fire (火). The combination suggests the idea of fire, which is often red. Over time, the form of the character evolved, becoming more simplified, but the core meaning of "red" related to fire and eventually extended to the general color.
