Groomsmen attire for dusty blue colors?

Hi ladies! So my wedding is in December and our colors are mainly dusty blue and dusty rose, along with other blues and pinks as accents within the color spectrum. My bridesmaids are wearing these beautiful dusty blue dresses and I love the color, but we are having trouble figuring out what the groomsmen should wear? I don’t want to over do the blue with navy tuxes but I also don’t want to do too much gray because the dresses have a very gray undertone. Should we just stick with black tuxes? I’m fine with that because I’m very simple and classic but my FH is less traditional and likes more color/uniqueness. Thought about dark charcoal but just not sure what to do especially with tie colors too. We are stuck on what to do especially for a winter wedding! Any advice??
