There is no difference between red self and red tabby. Therefore you can have for gene A the following combinations: AA, Aa, aa.

Where do I find such colours like cinnamon and white ? Or cinnamon tortie and white ?

Normally you will not find cinnamon/fawn (tortie) and white in Persians or in the Semi-Longhairs. But you'll find them f.e. in the Rex, where those colours are recognized in several federations.
But recently you can find cinnamon/fawn (tortie) and white also in the Orientals, they look quite nicely. Bicoloured Siamese and Balinese are sometimes called Seychellois.
By nature such colours are not impossible, but they are still rare, because those colours are not recognized in many federations. That means it is only a practical reason that breeders do not breed for such colours in other breeds, because those cats won't become Champions.
You can find all other Bicolour varieties in many breeds, as in Persians and Exotic, British Shorthair, European Shorthair, in Ragdolls, also in Manx, in Japanese Bobtails, and so on.
