I bleached my hair and threw away the bottle that had the bleach in it. I had the garbage bag hanging?

on the doorknob and when I woke up the next morning some of the bleach that was left in the bottle leaked through the bag and onto the hardwood floor. I wiped it up (it's a good thing my maltese didn't lick it up while I was sleeping) but it left a permanent dark mark on the hardwood. Is there any way that I could make this mark look like part of the wood floor so that it wouldn't show as much if my landlord ever had to come into my apartment?
