There are stereotypes with cat colors. Reds/gingers/oranges are supposed to be laid back. Torties have "torti-tude". My black cats have always been very loving and playful. My grey's have always been little love-muffins.
There has to be something to it, and it probably has something to do with the owner and the size of the household. I can't get enough of reds, greys and blacks (they all get along with each other). I have never had any luck with torties and brown tabbies - too much attitude to fit into a large household. Too much white in a black & white cat also gives me problems.
Someone mentioned that they get their personality from their father. I know for a fact that genetics play a large part of their personality. I bottle raised a litter of 4, kept 2 and adopted out 2 to a very close friend. Since we live 600 miles apart, we constantly compare notes about these 4. It is amazing how much alike they are, even though we separated them at 5 weeks old. Weird things like how they jump, how they eat, when they like to snuggle, where they hang out in the house, etc. I'm not sure it all comes from dad, but it certainly is carried in their genes (and to break the color stereotype - 2 are black and 2 are red).
And for every stereotype, there are tons of exceptions.....
