this may be the "breeders" corner, but we are from all over the world, for example, you are in Finland, where as I don't even know where Finland is I am from the states, cat colors in your corner of the world are called completely different things than they are here, I've come across several US breeders who call their calico cats calico, because that is the accepted term here, tortie and white is the accepted term in Europe. It doesn't mean "calico" is an incorrect term, because here it's not.
I did not say calico is an incorrect term either, it is accepted in CFA (which was just discussed in another tortie-related topic here). I might be from Finland (which is in Northern Europe, bordered by Sweden, Norway and Russia) but I actually breed under TICA, which is an US based registry. (I have to deal directly with their US office when I register kittens for example). The term 'tortie with white is used everywhere in the world, also in US (like TICA & FIFé), whereas 'calico' is only used in parts of US (only recognized by CFA).
