Thank You.
You’re welcome. I’m not sure how much the light from the more distant galaxies and proto-galaxies were red-shifted to longer wavelengths, but their emissions have been in route for billions of years. In some cases, nearly 13 billion. However, I don’t think much if any, now observable in visible light, started out much shorter than UV. But I could be wrong.
