Summertime Green, when is it ripe?

[jenniedhs]

I have never grown a green tomato, nor a yellow. I have a Summertime Green and a Summertime Gold I am growing this year. I have read everything I can on how to tell when they are ripe, but it sounds like it takes experience! One Summertime Green started a little darker green, then got almost a white green which I know means they will start to color soon. It got a little bit greener this week and then felt softer when I gently squeezed it today and I could have sworn there was a "blush" (although very slight) on the bottom when I looked outside. I picked it and brought it in. I can't see a blush inside the house, maybe it was hopeful thinking outside! But it is soft when gently squeezed. Did I pick it too early? Or as in reds, pinks and purples at "first blush" so it will ripen up nicely on the countertop? I am not sure how I will know when it is perfect for slicing!! I hope Summertime Gold will be a little bit easier to recognize when it is ripe. Any guidance would be most appreciated!
