Chestnust is more a brown with a hint of auburn
I wouldn't know that in depth as I have never coloured all my hair, have always had highlights , but I understood that chestnut was red brown. But I'll take your word for it Shelley :)
Eastern European red
Do you think Jonathan Ross's wife had her hair coloured that red you refer too ?
