Looking for sunlight resistant stain

[smorgasbord]

I've been using Sutherland Welles Old World Concentrated Stains for decades, and have gotten great results - except for a few pieces/locations that get a lot of sun through windows (non-gas filled). I'm replacing the skylights in the house with the latest Velux, and opted for the stain-grade wood interior. But, it needs to be stained to match the rest of the house. Obviously, I'm worried about UV caused fading.

Now, maybe the new E-glass from Velux will help reduce UV rays getting through, but probably not enough to prevent fading - I suspect that's mostly about heat transmissiong (which is IR, right?). Anyway, I think my choices are:

1) Get a Gel stain that comes close and use that. Overcoat with my normal Murdoch's finish (also from Sutherland Welles).
2) Use the SW stain I've been using and topcoat with a Spar Varnish, or a boat-type Polyurethane (Smith & Co makes one) that has UV blockers in it.

Other ideas for me? Skylights will be delivered in a few weeks, and I'll have a month in which to stain/finish them, so multiple coats are an option.

I had the same issue early last year with the inside of a large window frame that gets direct sun all day, and went with an exterior grade Marine varnish, Bondall Monocell Gold to be specific. Happily it's still like new, whereas prior finishes would start deteriorating after some months.

Just to be clear, my only issue is color fading, not actual deterioration

Colour fading and varnish deterioration was my concern as I had ebonised the inside frame. I'm very happy with the results of such a high sunlight exposure area after 1.5 years using the marine varnish.

Would the marine varnish protext the dye stain underneath?
The kind of fading I'm seeing takes like a decade to be noticeable with my current stain and oil finish.
