I'm personally not a fan of tile - very hard on the feet, I find - so I'd probably restrict tile to the wet areas and go for hardwood everywhere else. Our last home had wood in every room except the bathroom, and after 10 years it still looked fine. Even the kitchen looked good. That said, we didn't have kids running around in the house. Did (and still do) have a dog, though. Our current house has carpeting in the bedrooms, engineered wood in the living areas, and tile in the bathrooms and laundry. All three floor coverings have a similar greigish tone, so to my mind they look fine together, and meet the practicality and comfort criteria as well.

Is the pic of the house attached to this discussion exterior rendered in Taubmans pebble bay?

With a million variations through a million computer screens you will get a million suggestions and very confused while no closer to your answer. You have to do the work yourself and either get a colour match to a chip the min of a 50c piece or buy a Dulux or Taubmans fan deck and select a colour as close as you can. Alternately get a professional painter or decorator to use their fan deck or atlas to colour match for you and be prepared to pay them for their time.

siriuskey we have a builder, may have to see what their 3rd party renderer thinks, else sounds like a good idea to just drop into a paint shop and talk ideas with someone.
