The kanji 紅 is a phono-semantic compound (形声文字). The left side is a radical called 糸 (ito), meaning "silk" or "thread." The right side is 工 (kō), which originally represented the sound. The combination suggests that the character was created to represent a red dye made from silk threads, reflecting the color red. Over time, the meaning broadened to encompass anything red.
