xbuzznshellzx, check out the post by buttrfluttr in this [old thread[(https://www.houzz.com/discussions/benjamin-moore-paint-in-austrilia-can-i-match-dsvw-vd~799560). If no luck doing it this way try order the BM paint card samples then take into any store that has a spectrophotometer. They can do a read on the sample to work out a formula.

what bedroom furniture do you have

I think you really can't go wrong with Natural White, but I would try continuing the Grey Pebble and just being mindful of introducing surfaces that will reflect the light such as a big mirror, a large light coloured print and some light timber furniture. And of course it's a great opportunity to introduce some amazing lighting!

Don't make colour decsions based on digital photos found on the internet. They are only indicitive as there are too many variables with lighting, angles, and screen adjustment to be accurate. The ONLY way is with real samples, on-site at different times of day. Best of luck, Dr Retro of Dr Retro House Calls
