Hello,
I had to change the shower tray and hence the contractor had to remove
the tiles above the shower tray.

I got the tiles from Lowe's. When the work is completed, I see a
slight difference in the color of the tiles. Now, I am not sure what
to do. At least I should have got some contrasting tiles but I think
its too late for that. The contractor is asking $1000 for redoing the
tiles from top to bottom. I am not sure what to do. Any advice is
really appreciated.

Thanks,
Steve.
