Googled the karaka tone - consider resene ash - closest to a creamy white when you see it on the exterior. Depending on your house style, (more cottage like) I'd contrast the karaka green with a near white tone rather than a khaki tone. More modern, more khaki.

Hello Lisa..thanks for your comments - so kind of you. The pictures are not good (sorry) and to be honest whilst I'm renovating I don't have the courage the post much at all ..well at least until it's finished but here are a few enclosed. My real idea is to get a discussion going that we might all enjoy. and yes how light strikes (as in angle?) can impact on even the paint colour etc. I see so many questions from readers about wallpaper paint colour etc and yet experts and skilled people such as yourself will know that it's the cohesion that has to work and light can play such a huge part. A wallpaper can be purchased and then prove disappointing if used in different a light as can paint - which is why we use your good services where possible! I've a pile of boards each with different colours (I use linen style artists boards as I can shift them around - I leave a white border on them to allow a suitable contrast) The small bedroom picture with the striped curtains was more to show that curtain colour - it's now blended with duck egg blue paint (sorry it's a New Zealand company called Resene's so it won't be known of there but called Robin's Egg Blue), ivory carpets which I had edged in a green/blue wool. Before these drapes (Laura Ashley) were in a different room and just didn't work. The bedroom hasn't been finished (See? I'm still a tad embarrassed) but I mentioned these as with incandescent lights this curtain colour did not work at all. Taking my courage in both hands and uploading a picture of the main living area which is to be painted next to do away with the strong saturated green..very dark and gloomy as the natural light is very limited. Hoping you can't see the paint splotches on the wall. Another lesson I learned is to paint a surface white and THEN paint the choices. If we don't do this the original surface colour 'bleeds'. So I really hope to have others including myself recognise that we have to have one eye to the climate and outdoor colours all the time as well as the same paint colour possibly being different from room to room. Regards...and thank you once again for taking the time to reply.

My vote is for the wash but not in bright white and after some selective knot primer in the same tone. You are going to want to selectively primer down about 2/3 of the knots (use a dark white tinted primer), and use a dark white / brown toned off white instead of bright white so the beams still give you dark white on bright - that would be my vote. Consider something like bm stingray tinted primer and wash on the beams. You can add glaze for more working time or put down dropcloths and use water to cut it into a wash. Test it on some other raw wood that has had tannins develop for a few years. Then put it against your white wall - your husband will get the contrast and wood grain but you'll get the quiet palette you were hoping for. They both will have architectural depth and interest.

Yay! I'm so glad it all worked out and you love it. Who cares what people think, as long as you guys love it! You're the ones who have to live in the house anyway haha - pops of colour are great! Do you mind putting up a photo of the room? I'd love to see what you've done with it!
