I would go with red. Nice pop of color.
I have a love-hate relationship with nude color (rose poudre). I agree it looks smashing on the shelf.. but I struggle with styling it. I know it’s a neutral and “can go with anything”... but I always feel like it doesn’t go with my wardrobe! Maybe because most of my clothes are bright or primary colors. I don’t know. Maybe it’s a mental barrier.
I love pink but would not buy a nude/super light pink. The lightest I would go (for my wardrobe) is Barbie pink.
Anyway. TLDR: check your wardrobe and see which color would match more of your common outfits.
