That's a solid hardwood, the 3-1/2" width makes me think it is an import (Chinese) product. I'd also lean towards it being a maple or possibly birch. That combination of factors has it most likely coming in via container loads, so it could quite possibly be long gone from any retailer.

Best bet may be getting a putty pencil/colour filler product for it. Finding an exact match is going to be tough.

Edit: Some of the ideas of sanding off the affected area and trying to stain may work too. There is a stain product out there called Saman that has a lot of different colours available.
