Have to work out skin type?But contrast in hair/eyes making it difficult?

I'm working out my skin type for biology. But when I research it on google it puts blond or chestnut hair and light eyes and extremley pale skin and freckles in the same catogary and brown eyes and brown hair and skin that tans in the same catogory.I have dark brown hair and blue eyes so Im confussed where I fit in the catogory's.I have pale skin but its not the most whitish shade, Lol and I do tan deeply in summer.Dont have alot of freckles either.Am I just a misfit in this catogory? lol
