The kanji 易 is a phono-semantic compound (形声文字; keisei moji). The top part of the character depicts a lizard 蜥蜴 (tokage) or chameleon that changes color easily, and the bottom part of the character resembles the sun 日 (hi). Thus, the meaning evolved to represent something easily changed or something easily adaptable. It originally depicted an image that changes according to circumstances, and gradually came to mean "easy" or "change."
