As one of the few, it seems, who like the little pear tomatoes, I think a very orange one would or could be interesting, too.

The tangerine gene is the most common cause of orange color in tomatoes. A cross between such an orange tomato and a yellow (or red) tomato will produce a red F1 hybrid.
There is less-common dominant mutation that results in orange fruit. It is supposed to be present in: "Caro-rich", "Podorok Fei", "Jaune Flammée", "Caro-Red", "Big Orange", and "USDA 97L97". It is probably in a few others, but if your orange variety isn't in this list, you're probably dealing with the tangerine mutation.
