With regard to my previous reply about blue roan and tan being a tri-colour, apart from the classification in Judy de Casenbroots book, the same classification of tri-colour is also in H.S.Lloyd's book, The Popular Cocker Spaniel page145 (4th edition), and in The Cocker Spaniel by V.A H Mathews (1950) page 175 she classes a blue roan and tan as a roan tri-colour. So if they aren't now classed as a tri-colour, what is their colour classification?
