Question on white tomatoes

[ubergoober]

I may possibly have a White Wonder in my garden this year. It was one of the varieties listed on a mixed seed pack that we are playing "Guess The Mystery Tomato" with. lol

Now...how does one tell when these things are ripe? The plant that I think MAY be a WW has VERY light coloured fruit. White with a slight tinge of green to it. Am I looking for a colour change or do I have to fondle the fruit? :p
