Beautiful vintage ceramic tile by Color Tile.  We bought these for our bathroom remodel, and have some left over!  They are a lovely mid century aqua color.  Closest color I can come up with is Spring Green or Ming Green. Please see pictures.  Most of the tiles are in perfect condition, but a few have small nicks.  The back of the tiles have varying amounts of residue from prior installation?  I have not tried to clean it off.  We are not tile experts, just want to share our love for all things vintage.
