“Jewel Tones” or “tiffany Blue”

We are in a bit of color scheme dilemma.
Our wedding is in October 2020, so I know I have a little bit of time to plan and things but I think that a color scheme is where all the details start!
My original plan was to have my MOH in a dark teal dress (peacock shade from Azazie), FH and BM in navy suits with ties in the Peacock shade. Flowers were plum and purple flowers. Tables with white linens, with navy napkins & chair sashes. This was my take on jewel tones.

Now... FH has a Tiffany & Co. “Tiffany blue” tie that he really wants to wear with a silver-grey suit.
So... tonight I’m thinking... FH and his BM in the silver-grey suits with matching Tiffany Blue ties. MOH in either (1) dark grey or (2) Azazie Spa or Turquoise (have to see the samples to match the Tiffany Blue). No clue what color napkins & sashes or flowers. I feel like the entire scheme is too springy and I don’t what it to look like a Tiffany store.
Or if I combine the colors I feel like would be too many (adding the grey suits & Tiffany ties to the darker scheme).
What are your thoughts? Suggestions?
Thank you!!
