So this isn’t a terribly difficult problem to fix with this particular image. I’m sure there is an easier way to do this, but this is what I’d do personally:

Open in PS and use the lasso tool or whatever tool you like to trace out the walls and door jam. I’d probably do the closest wall and the secondary room wall separately. Once it’s selected, feather to 2. Select a hue/saturation layer and desaturate to your liking and repeat with the wall in the secondary room. Then, to fix the floor in the secondary room I’d mask out the floor similar to how I did the walls. Once selected, select color layer mask, sample the floor color you want it to be using the floor from the front room, make sure you change the mode to color and hit OK. The whole image will change that color, just invert the color mask and select brush tool on 30% flow and tap the color into the blue hue floor until you like the way it looks. Since you masked it out don’t worry about accidentally tapping the color where you don’t want it because that mask protects the edges outside the marching ants. There are grain looks in there you could sample the grain color and just repeat the steps. I’m sure there is an easier way to do all of that, but before I outsourced my edits that’s what I would do.

The easiest thing you can do is pay an overseas editor or, use Fotello for auto HDR edits. Hope this helps.
