Go for it! Dye your hair purple (there's a poem about that; I'll see if I can hunt it out for you) get a tattoo and make Zandra Rhodes look like Hyacinth Bucket by the comparison
I too find family hair/eye colouring genes fascinating. Haven’t got a clue really as to how they work, but still find genes fascinating.
My dad had jet black hair when much younger; the sort that looked electric blue in places like a magpies black bits.
Mum had silver blonde hair when a child which turned a dark blonde/pale mousey brown as she aged. As such she was forever dying it since her late teens; everything from platinum blonde to rabid redhead. It was really disconcerting to set off for school with a blonde mum in the kitchen, only to return home early evening to this redheaded ‘stranger.’ Being a redhead suited her, though.
However, both my brothers and I have really dark hair, but not blue black like dad’s used to be. Mine’s darker than my brothers being a sort of dullish black, but no shiny blue bits when the sun shines on it unfortunately.
My dad’s family is weird. Three of his brothers and his one sister are tallish, blue-eyed blondes (taking after my granddad) and he and three other brothers are shortish, greenish-eyed blackheads, taking after my nana.
I remember turning up to some family do and several of my cousins (all kids from one uncle), seated along the back walk looking very severe and unfriendly, all had white blond hair and very pale blue eyes. They looked like the kids from the film ‘The Village of the Damned'
The really did look like the kids above… Freaky or what!
My hair too is beginning to go grey. However, going by these renegade grey betrayers it looks as though my hair will eventually go snow white, just like mum’s ended up.
Eventually, I too will get fed up of dying the roots but, to kind of quote St Augustine, “God make me grey, but not just yet.”
Until that ‘fed up of this dying lark’ day arrives, I’m sticking to Superdrug’s Colour Performance 3.0 Natural Darkest Brown. I mix it with a squirt of SD's Natural Black 1.0 as their darkest brown isn't quite dark enough but the black on it's own is too black making me look like a Irish barmaid....
