膚色、髮色及瞳孔顏色均是由黑素細胞(Melanocyte)所產生的黑色素(Melanin)而定。561Please respect copyright.ＰＥＮＡＮＡh9WLFAuayW
然而，負責膚色髮色與負責瞳孔顏色的黑素細胞卻有著一道顯著不同的分別。561Please respect copyright.ＰＥＮＡＮＡYzaf7gQxL6

（圖2）黑素細胞所產生的黑色素，會儲存在名為黑色粒子的細胞器官裡頭。561Please respect copyright.ＰＥＮＡＮＡvHxHV7YO4p

位於皮膚下的黑素細胞，會釋出黑色粒子到髮囊及皮膚細胞，賦予皮髮顏色。561Please respect copyright.ＰＥＮＡＮＡoWtPtqi87A

而位於虹膜(Iris)的黑素細胞，則不會釋出黑色粒子到細胞外部，而是把它儲存在細胞內。561Please respect copyright.ＰＥＮＡＮＡ4stFrSEa5E

（圖3）當光線進入眼睛的虹膜，內部蛋白質所折射及吸收的波長便會呈現出瞳孔的顏色。561Please respect copyright.ＰＥＮＡＮＡ7DYOMU23W0

瞳孔之所以呈藍色，並不是有著藍色素的物質，而是純粹因為虹膜內的黑色素稀少，最終折射出藍色波長的光線。561Please respect copyright.ＰＥＮＡＮＡ0ZhAhckV9z

虹膜越多黑色素的話，瞳色便會越漸啡黑。561Please respect copyright.ＰＥＮＡＮＡWSIh3ynTyY

而患有白化病(Albino)的人士，基於缺乏黑色素，光線折射出眼睛內血管的顏色，因而呈粉紅色狀。561Please respect copyright.ＰＥＮＡＮＡYDWVS3jah3
