The SW sample pots are huge, get them to colour match a smaller one. If you paint a couple of cardboard sheets you can stick them up in various rooms to see it in different light

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!

have you ever try Wall Mural, it will colorful your room , and extend you vision.

Hi, I don’t know if this helps but in out Reno we did last year we chose lexicon quarter for our walls. I don’t regret it as it suits what we did style wise, and it is a ground floor apartment so needs the extra brightness for reflection - it was previously painted hogbristle and looked really dingy and dark. I agree with the above comment that lexicon is stark. For our new house I’ve gone with Surfmist outside and a warm light grey inside - so two warm tones, but that’s because I wanted a more cozy feel as opposed to a fresh and bright feel. I don’t think it matters on outside vs inside though, I think it really depends on your furnishings and fixtures/floors etc. For example I personally wouldn’t paint my house lexicon if all of my furniture was rich wood and warm tones.
