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。457Please respect copyright.ＰＥＮＡＮＡdvq8GaM5Ta
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。457Please respect copyright.ＰＥＮＡＮＡDjY1SY2xY4

（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。457Please respect copyright.ＰＥＮＡＮＡBCPP2RR2a3

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。457Please respect copyright.ＰＥＮＡＮＡ0VsKtmhcWx

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。457Please respect copyright.ＰＥＮＡＮＡz7d6PquGab

（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。457Please respect copyright.ＰＥＮＡＮＡc3N0iynqgy

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。457Please respect copyright.ＰＥＮＡＮＡ36f2epei5p

虹膜越多黑色素的話，瞳色便會越漸啡黑。457Please respect copyright.ＰＥＮＡＮＡ3rpzdnkz3R

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。457Please respect copyright.ＰＥＮＡＮＡW5iQA1jY4D
