Taubmans chilly water (more green) or misty rain (more blue). i'm sure there was a design dilemma post from a while back that gave the Aussie paint answer to this question. Hopefully someone who knows will see this and link it.

Cream always looks good with green, maintain the same green for windows & door. Having said that you can choose any colour by repainting the gutters & fascia etc. Get lots of colour swatches & hold them up to the roof (from a distance) to see what looks best to you. Then get some sample pots & paint so you get the proper effect of the end result. Look around at other painted homes & magazines etc, to get an idea of what you really like.

Both colours would look good with the flooring you plan Is the brick wall staying? The darker shade would balance the strength of the brick colour The white kitchen will make the whole room blend together as it will 'clean' the colours consider how you intend to decorate the area - is the green going to feature heavily elsewhere? (like living spaces?)

Warm white or greys would work well for walls. https://www.dulux.com.au/colour/whites-and-neutrals/most-loved?gclid=EAIaIQobChMIwbzrqZaM2wIVzTUrCh0ALAneEAAYASAAEgLvKvD_BwE&cid=ppc%7Cgoogle%7Cdulux.com.au_main%7C%7CSpring_Oct_2017%7C%7C%7C%7C%7C%7C%7C%7CBrand+-+Colour+-+Specific%7C%7C%7CBrand+-+Colour+Whites+-+EM%7C&s_kwcid=AL!4713!3!266934234389!e!!g!!dulux%20warm%20white&ef_id=Wv0opwAABZ8L@CUB:20180517070055:s
