We have a pine floor (not recommended, too soft.) It's finished with a
typical polyurethane (I assume). The problem is the color is changing
under a rug. We had one in the kitchen, and it was lighter under the rug.
I owuld have thought it would be lighter where the sun was bleaching the
floor, but the opposite was true.


Some woods lighten, but most darken from the sun. The UV rays make a big
difference. Try cherry and you will see a big difference in a day or so.

Three solutions.
Sand the dark area to remove the top portion that is dark
Remove the carpet and let the rest darken
Astroturf
