The kanji 混 is a phono-semantic compound (形声文字). The left side is the water radical (氵or 水) meaning water, and the right side (昏) is a phonetic component that provides the sound and contributes the meaning of "dim" or "dark". The combination suggests a blending or mixing of something, perhaps originally referring to the murky appearance of mixed water. Over time, the meaning expanded to encompass mixing in general.
