Sage, ivory, copper color scheme?

What color blue, like Navy, light blue? What color tie is he going to wear, just Ivory?

I don't think blue would look bad, with Sage color I've always seen guys in tan suits.

I think blue would look nice, especially if his tie or boutonniere brings in the other colors -- but I also may be a bit biased because we did navy, grey, copper, sage and ivory as part of our palette.

All the colors you mentioned are earth-y tones, so you can't really go wrong!

I think those colors sound beautiful and feel like they would look nice with a dark blue suit.
