Oh no that's a shame!
If there is any way you could find a contrasting coloured tile, and somehow spread them out across the area, so it looks like it was always meant to be that way, that might be your only option short of a full re-tile job.
Is Aydos the tile name? Don't suppose you know if it was Topps' own name for the tile and it actually had a manufacturers actual tile name in stores that aren't topps?
Long shot. Just wondering.
I used to work for Topps (a long time before those tiles were in there mind) and whilst they are huge, and did buy their own tiles in and name them, sometimes they did buy tiles that other suppliers sold too, and just renamed them inhouse.
