All tomatoes start out green. Whether they end up green, yellow, orange or red when fully ripened is a matter of genetics. Generally, the yellow and orange ones are less acidic (which in some people's minds makes them "sweeter"). I love them all (and grow them all). In fact I have 48 peat pots with various tomato varieties growing in them right at this moment (just waiting for hubby to move his storage crap out of the greenhouse so I can turn on the heater and move the pots out of my kitchen and into some real dirt lol).
In case you were wondering (probably not lol) BELL peppers (not the hot types) are the same way. They start out green (tangy) and end up red. If you've noticed, red bell peppers are usually the most expensive in a grocery. It's all rather silly since if you leave the one that is already yellow/orange on the vine a bit longer it will end up red anyway.
by the by, I have put yellow pear (cherry-sized) tomatoes in "fruit" salads and no one has EVER complained.
All that being said, yes a tomato is, botanically, a fruit, not a vegetable.

As much as I love my friends, I won't jump off a bridge WITH them. Instead, I think it's in our mutual interest for one of us to try to catch the other when they fall.
