Darkening grout/tile on tumbled marble backsplash (pre-grout sealant used)

Hello all:
I wish I read this site before our tile job - incredible info on here!
I have read many, many posts, but am still uncertain as to how to proceed.

Here's my problem:
Yesterday we sealed our tumbled marble backsplash 2x with penetrating sealer prior to grouting. We loved the color of the tile. Today, our contractor came back and applied the grout and when we got home tonight, the grout and tile now looks too light. We haven't touched it so far.

Do we:
-use a vinegar wash to remove any potential haze? if so, how long do we wait before doing this? is it safe?
-scrub it with warm water and rough sponge?
-apply a colour enhancing sealer on top?
-attempt to remove the original sealer (used pre-grout) and re-seal with a colour enhancing sealer (not sure if this will even work given there is grout ontop of the tile now)? Again, if so, how long should we wait?

Thanks in advance to anyone who offers advice.

if its just a light haze on the tile I would clean it off.
if the grout was too light and filled the joints, plus the small divots in the tumbled marble, most likely your seeing a visual trick where the light grout makes the tile look lighter.

after its clean you can try applying the sealer and see if it darkens it.

I had the same visual effect after I grouted my travertine tile that had been sealed prior to grouting using Aqua Mix penetrating sealant. I applied a color enhancing sealer as I was not happy with the look and it turned out very well. It darkened the tiles somewhat but, probably due to the prior sealer application, not as much as on an unsealed tile.
