Here are links to 2 older threads that may be useful to you. The common suggestion is steer away from cool or stark whites with this stone. It might be worth seeing how 1/4 strength antique white usa colour looks with Frosty Carina. Or 1/4 or 1/8 strength beige royal?? This colour at full strength is suggested in one of the links. It also is paired with antique white on dulux colour wall.

What a lovely kitchen. Good idea to match to window and bi-fold. Gorgeous splash back tiles and the black pendants are perfect. I also spotted the clever used of space with the bank of drawers in wall between oven and L-shaped counter.

I think they would look great and give a real contrast to the area and such a great price, some stools are so pricey but Kmart do fabulous replicas of designer pieces, this Hendrix stool from Zanui is $299.95 very similar.

I think you should lay the floor first as I'm almost certain it will change your benchtop choice. There will be very little contrast in that space once you install a washed oak floor. I understand the reaction to the dislike of the current benchtop to choose a really pale one. But you may well decide on more definition than those very pale choices provide. If I look at all the modern white kitchens they typically have a large dark contrast area in the room to bring out definition.
