The kanji 皇 is a 形声文字 (keisei moji), a phono-semantic compound character. It is composed of the radical 白 (byaku - white, pure) and 王 (ō - king, ruler). The character also incorporates the element of "玉 (gyoku - jewel, jade)" which is often associated with the character 王 (ō - king, ruler). The upper part 白 (white) originally suggested a head, and the entire character represented a superior king. Over time, it came to specifically represent the emperor, the ultimate ruler, emphasizing the sovereign's elevated status and authority.
