Congratulations on your new home! I personally favour an all-white interior, but I think it will also depend upon what you plan on doing with the ... colourful carpets. I'm not sure how they'd all look with white walls as they'd really be attention grabbers! I'd potentially start by painting the ceilings white - I personally, particularly don't like the darker ceilings in the bedrooms and blue hallway. I'd also potentially consider picking two or three of your favourite colours from the house (e.g. the hallway blue and bedroom green) and using fewer colours, but consistently throughout the house (instead of every room being a different colour). You could do all living areas in colour X and all bedrooms in colour Y. Good luck!

There are so many things to consider, for example the orientation of the house is it a North facing yard which will attract lots of natural sunlight, where South facing is shaded and colours will appear deeper / darker. What colour are the gutters and fascias and roof? Aluminium windows are these pearl white? As you probably know there are many shades of white, that have very different undertones, some throw red, blue or yellow. From the samples you have painted you appear to be drawn to a "greige" combination of grey and beige a smart colour for todays exteriors so certainly on trend. A lovely greige I have just recommend for a client is a Deluxe colour called Calf skin, paired with natural white trims and a grey pebble large garage roller door has come up beautifully. If you are in Sydney happy to assist with a colour consultation. Worth the money

Really hard to tell. I like the lightest one but I'm not very adventurous. You may need to choose one and paint a larger area and see what you think.

We recently updated an apartment to sell and got great feedback from the buyers on the paint - Dulux 1/4 Lexicon low sheen on walls and Vivid White high gloss on doors, picture rails and trims.
