are these off color delicata squash edible?

any idea if there would be a change in taste?

Don't know with delicata...
This summer I saw some colouring on the striped cushaw, which when I went to collect turned out to be rotting. Good for chickens, but unappetizing to me.
Nothing like cutting them open to see...

I googled it:

How do you know when delicata squash goes bad?
You'll know delicata squash has gone bad if it has wrinkles or soft spots.

The vines look completely dead, I don't think they are going to get any better, than whatever they are now.
