If you take a sample chip of Polytec Essential White into Home Depot, they can put it under their scanners and do a colour match.

I am about to start some alterations and the front door is currently dark violet purple but soon to be black. I will however be retaining the natural rimu on the inside even though my kitchen walls are dark charcoal currently. I like them so much the new kitchen will have the same coloured walls. The new sliding windows in the kitchen have a pine frame so won't match the rest. I am going to paint it dark charcoal too, with the cedar sliders and rimu finishing.

Could you get surfmist in half? I didn’t think that was possible. I’m currently considering surfmist but wondering how it will turn out. Do you have a pic!

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!
