We have old Tasmanian Oak floors that are a warm light toffee colour and painted our walls in a slightly cool white (Caspar White Quarter) and to me it jars a bit as it makes the wood look more orangey. I wish I'd done a white with a bit of warmth (though stay away from daggy creamy whites!). Dulux Natural White I think is perfect and I've seen it used a lot and always looks perfect. (Though get Haymes paint, it's much better, the paint shop can mix it up in any brand's colour).

I love the various complimentary colours too . One thing that may be worth a try to really tie it all together would be a concrete or block surround of the yard / driveway tiles , in white or english cream . Your front fence has light mortar , the house walls features light highlights , and the terrace tiles have quite a light tone too -- by adding a small amount of that in the front yard , you'd add some continuity IMO . Pot colour would depend on your roof colour and overall taste -- there are some amazing blue and green glazed 'Eygptian' type ones available , differing sizes and prices , that often have swirls of colour -- or bright yellow or orange if you want them to stand out , while gloss black ( with crisp green leafy plants , or even red leaves ) pots are fairly neutral but also classy . Just my amateur thoughts .

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.

I would go off the code numbers for these first, as surprisingly the names can change in different countries.
