This is a basic caddis pupa pattern I have really had a lot of success fishing across and down. I added a twist and veiled the thorax with an antron/antron-like material.
" Both the pink larval and pupae of this tiny caddis often form a food supply in the drift that concentrates trout in or below riffles that contain high numbers of these caddis according to Gary LaFontaine in his book, “Caddisflies”.[b]"
Chuck, I think it will work well for you. Let us know!
PT: I think you’re right. Even in caddis pupae which we consider “green”, there is a part of what I would call “pinkish tan”. For example, the Apple Caddis Pupa.
Of course, you can have a green body and pinkish tan thorax too.
Here is a close-up from the wonderful website “Troutnut.com” of an Apple Caddis pupa and another fly like the pattern above with a green abdomen.

Keeping in mind that when wet and in the current, the partridge fibers undulate and mimic the legs of a struggling caddis pupa.
