Help with GAF Slateline Shingles Needed

We are working with a Homeowner’s insurance to get a roof replacement approved. Adjuster said it was a go, supervisor kicked it back saying they wanted to know what GAF Slateline color the existing shingle is that has been discontinued.

I’m thinking this may have been originally called Slate Gray but now has been slightly modified and named English Gray Slate. Would like confirmation prior to proceeding.

I have a call into the local GAF Rep awaiting a response.

Below are a couple of pics, perhaps that will help.


Couldn’t get the pics to upload for some reason.

After a search I found Slate Green Blend to be discontinued. But that is all I could find.
