A mid oak colour is very versatile.

Thank you. The finishes meet in the doorway in the picture as well as at the top of the stairs which is where the Lifeproof is installed.

If you were selling , are you sure you will recoup the extra $$$$ ? Get it wrong , and a potential buyer will walk and/or offer $50k less , whereas if you leave it as it is , they will know it needs replacing , offer $10k less , but you have gotten an offer ! Just me , but what I would do is rip up the fake tile lino in the foyer ( I assume it is lino -- it doesn't look to be 'proper' tiled ? ) , and do that in a darkish timber laminate -- slightly lighter than the front door , slightly darker than the stairs . Or go really dark -- almost a dark weathered grey or a similar dark brown to the drawer unit in the lounge -- the rest of the colourings will lighten it a bit , but it will all tie in . OR actually tile it , maybe a black or charcoal gloss marble or marble effect with lighter streaks through it ? The house and colourings look an older style , this continues that theme , but I feel white or beige tiles would look too bland . $2k max instead of $10k -- marble tiles may be more than $2k , but up to you .

The sample in the pics does look a bit yellow. I’d stay well away from anything with a red or yellow tone. I love your ceiling and it’s a feature to try and keep but as it is domineering you need to be careful of your other choices. Is the sample board a pre-finished board? On one hand that’s good because you can see the final colour but on the other hand it’s bad because the final colour is lot quite right.
