The kanji 虹 is a pictograph. It depicts the shape of a rainbow. The left part of the character represents a "虫" (mushi), meaning "insect" or "worm" and the right part originally depicted a semi-circle, which gradually evolved to its current form. The ancient Chinese believed that rainbows were a type of celestial dragon or snake. Over time, the character evolved to more directly represent the rainbow's arching shape and was associated with the colors seen.
