Looks good to me. Nothing wrong with a little pink.

Perfectly fine. Finish all the remainder and carry on

I love it..

Gray is on it's way out and the natural color you have is going to be more inviting. It will be a perfect backdrop for you new space. Enjoy it.

Red oak is going to show red once 'dressed'. Gray is not a natural color for wood--it has to be bleached and colored to get that ugly gray people embraced in the last decade. If you don't care for the red oak stop and choose another wood.

Thanks for the feedback. Overall, it's good, but some boards appear red in certain lighting. FWIW I originally wanted a medium brown. Would using a pink blocker on the remaining boards be worth it?

Change the lighting to LED 4000K and that might help but red oak is by nature red . I think to start messing now with different areas will just add to the mess . Once furniture, rugs art etc are in it will be less of an issue.

Gray lovers: If you must, put it on your walls or rugs or furniture, not your floors. This unnatural driftwood look on wood floors takes away from the wood's warm, natural appearance. No wonder it's on its way out. Very often a room with a lot of gray is enhanced by wood accents and floors in a natural wood color. More natural looking wood finishes add contrast and warmth to a mainly gray room.

A darker stain will tone down the red. Since you said you wanted a medium brown I think you need to go darker and less gray. I don't know which brand you're using, but Provincial and Jacobean are popular medium browns.

I chose Duraseal for the floors. Jacobean was an option, but I felt it would be too dark. Would it be okay to keep the upper floor in Duraseal and the main floor in Jacobean for design? Or should I use a neutralizer and stick with Classic Grey for consistency? Just to clarify, I'm not a fan of grey floors, but I thought Classic Grey stain would reduce red tones. Here's my inspo:

The floor needed to be bleached beforehand to get the pink out. If you treat the unstained section of the floor at this point, because bleaching damages the woodgrain a little bit there’s no guarantee that the stain is going to look anywhere near what is already done. It is not a pink blocker… It is a bleaching process.

The advice I found from several threads on Houzz is to use a stain with a green base to neutralize the red. That means Jacobean or Provincial. You can dilute them if you want a lighter color that still tones down the red.

@mcarroll16 initially, I planned on mixing, but I was advised against it. Now, I'm considering this route to finish the rest of the flooring. Hopefully, they'll match the current color

This looks great. you dont want grey floors anyway.

Idk if it helps - I read that green in stain kills red and it makes sense.

Someone somewhere mentioned Varathan Aged Wheat stain. It does look very promising, but i have never tried it, so just sharing what i saw.

Thanks for your input, @kate787878. I saw the same suggestion and tried the Aged Wheat out of desperation, laying it on top of a red board to test (even though I know it's not the ideal fix). Unfortunately, it didn't help much. I'm not sure if I should experiment with actually mixing those two stains at this point. In the photo below, the right side is closer to what I'm aiming for, while the red pieces on the left are what I'm trying to avoid.

You should leave it the heck alone unless you are going to sand off what you just did. What you have is a beautiful classic, and will easily outlast all of the sad and tired unpainted neglected house looks.

What you have, is better than what you want. By a lot.

Anything you apply to Red Oak will bring out the red unless the stain you apply has an undertone of green to kill the red undertones of the oak.
