I would do a lighter floor. no need to match anything.

a light floor will help with the natural light in the rooms.

I am guessing this isn't your furniture.

the decor/design style and wall color will play a role.

will you only re stain the lower level or the whole house? Railings?

Thanks for the reply!

No, the decor or furniture isn't mine.

I was thinking of painting the trim white and the walls will most likely stay a light beige color or white.

The upstairs wood will be done in the same color I choose for the floors.

I really like the "Special Walnut" color from Minwax. Do you think that will go? Example below.

if you like it, sample it.

Here is your room with various floor finishes so you can see the result. You'll have to have the refinisher actually sample the stains on your floor, but this may provide you with the ability to narrow the choices.

Depending on how creative you are, this Coastline Dark Gray could be a very interesting addition to your home.

omg @BeverlyFLADeziner! This is sooooo helpful! Thank you so much!!

That ceiling is nothing special ugly pine. Shellac the heck out of it to seal in the knots and sap, and then paint it the color of choice. Then leave the floor be, as is. Warmer tones are back in style, and the pale dead body look of white washed floors has run it's course, as the super dark ebony did years before.

Do NOT paint that beautiful celing- it's a beautiful focal point n the room. In order to choose a color for your floors, review finish options in each room, daylight and evening illumination. Lighting can bring out surprising undertones . Beautiful rooms! Consider you may be putting in an area rug which can affect the finish color as well. Also keep in mind the window trim wood. They don't have to match perfectly, just blend together.

Good luck!
