Fountain Pens

Hello folks!

I'm still rather in the "shallows" as of yet, I have a handful of pens (Lamy, Platinum Preppy, Donegal Pens) and only a couple of bottles of ink (I rather like Noodler's 54th Mass.). One of the areas in the hobby that I'm least knowledgeable in is paper. So, I'm hoping that you folks have some recommendations, both for myself and my sibling who is a bit of a fountain pen enthusiast but has sensory sensitivities.

What are you favorite papers, both loose leaf and bound, for texture, color, and any other properties? Preferably, nothing too bright/with fluorescent pigment.

Bonus question: I really like muted colors (desaturated in digital-speak but I think that doesn't write mean the same with inks). Any suggestions for good inks on that category?
