Wood Floor Color Issue
It's almost impossible to to get a perfect color match with older work and new----the wood darkens and gets a patina within a year--so the older work will have a color tone that is darker and more complex than the new work.
If the tone change is unacceptable---then sanding the whole floor and restaining will be required.
Waiting for the new work to 'mellow' might be the ticket.also.
