We have Lowes "mesa beige" in our basement bathroom and foyer. The new lots of "mesa beige" from Lowes are now significantly lighter...so much as to make the original look "dirty" next to the newer dye lot. It's very hard to find something to adjoin the foyer tile that won't clash. We don't really want to tear up the foyer and start over since that was already a fairly recent expense. How can we solve this?
