Color Scheme... too much Gray?

Our wedding colors are Tiffany Blue, gray and white. I’m wondering if my new idea is too much gray...


Future husband and his best man (no other groomsmen) are planning on wearing light grey suits with Tiffany Blue ties. My Matron is Honor (no other bridesmaids) was going to wear either Teal Blue or Spa from David’s Bridal but now I think I want her to wear darker gray than the suits and the wrap for her bouquet to be Tiffany Blue to tie it all together. My shoes are going to be Tieks in their patent Tieks Blue.
I really like how the light gray, almost silver, table overlays look with white chiavari chairs and Tiffany Blue napkins look. Our table numbers are acrylic plaques painted Tiffany Blue with white lettering. All the other tables, gift/cards, cake, foyer and seating cards will be Tiffany Blue to match the napkins.
We get complimentary colored up lighting so that will be teal/Tiffany Blue.
Is this too much gray? I’ve looked on Pinterest and I think it looks beautiful! I want the Tiffany Blue to be more of an accent color rather than the primary color as originally planned.
TIA!!
