I agree with ctwalker, if you paint the inside of your front door white it will blend with the inside of your house especially as the door is in your lounge. On the outside a stain will look great and if you keep a path going to your front door people won't have trouble wondering where to go. All the work your doing looks fantastic keep up the good work :)

I think white walls would make the jarrah a feature, maybe antique white

In my last house, after adding a living room (the area you see this side of the arch) and also updating bathroom etc I couldn't afford to reline the ancient walls in my little lounge (when I removed the purple wallpaper I found a mixmax of boards, gib, pinex, plywood and holes!) so I plastered walls all over with layers and layers of newspaper and wallpaper paste (papier mache), then after applying primer/undercoat I painted with 2 similar colours (rich reds in this case), and stippled the surface with a plastic bag. This made it look just very slightly textured like leather and successfully disguised the uneven surfaces. Gallons of gap filler filled the gaps between the old T&G ceiling boards and evened out the mismatched skirting and scotia. Again white paint on all the trims. Amazing what can be done when you have to make do! This was a great cosy little room! (Before photo is the 3rd one)

I’d suggest using pieces of plaster, painted in your chosen colours, to see what the colours look like in different rooms and at different times of the day. We were always going for Natural White which ended up having a pink tinge in certain light in our home. Our large back area is east facing (8m of glass stacking doors) with two south facing windows and two large skylights for northern light. Our colour consultant suggested Dulux Snowy Mountains Qtr strength and it is great for our home. Not stark (no blue/grey tinge) but definitely not too warm. We went all the same colour - walls, trims, ceilings - just in different finishes. Modern home with squareset ceilings. White is so hard. Good luck with your choice!
