I would go with a gold or yellow ... of course I happen to love teal/ turquoise and gold/ yellow together. Something in variations on the photos below... maybe some pink accents if you have a girl or lime green or blue accents if you have a boy.

HI Madison There are pros and cons for every situation, but you need to work out what is best for your lifestyle. Personally, I agree with the carpet in the living room, and hard flooring in the kitchen/dining areas. All you need to do is work out your demarcation points (where carpet will meet hard flooring). A great retailer should be able to visit you at home, discuss options, give you pricing and away you go! (Us if you are in Auckland :) ) With littlies, I'd suggest a vinyl plank.....other posts will tell you I'm a big fan of it, but with kids, toys, mess, liquids etc, vinyl planks will give you the best wear over time. They are very hard wearing (Karndean have lifetime residential warranty), easy to keep clean, and waterproof - can be installed in all wet areas. Timber flooring, depending on which you choose (real wood, engineered wood, laminate), may not be the best "fit for purpose" products in your situation. Whilst I'm not trying to champion one product over the other, having had carpet with little kids, and putting drop sheets over carpet, under highchairs, why wouldn't someone not put in vinyl planks?

Without knowing any more info , I'd say its near impossible for anyone but you to know what colour/s to choose -- do you want the house to blend in but have its own style , or do you want it to stand out ? What colours are your main furniture items and even kitchen etc ? For xxample , if keeping the beige walls , how about doing the eves and gutters and garage door in a tangy ( bright , but not glaring ) orange -- this would work with the existing colours and not require a complete repaint . BUT if your kitchen was mainly various shades of , say , green and teal , and your lounge suite and duvet covers were mainly blue hues , that may 'feel' funny , clashing with the exterior ? Of course , blue and beige exterior may not work with the brown aluminium , as youve recognised . Another option ( a bit hard to tell from the pictures ) is that a light grey ( repaint the beige ) with mid-charcoal base boards may work with the brown aluminium , then a bright colour on the gutters and front and rear doors to suit -- anything from sea blue to bright yellow , orange , red , even white or off-white would probably work .

I would look at colour samples next to actual sample of the schist to be used. Take that to a local paint/render shop and look at them together. Looking at your image, the schist looks to be a golden schist rather than a grey. Is this just the way it has been shown? I would check with the suppliers for the actual colour of stone to be used as there are a lot of possibilities and the colour will affect your colour choice for the plaster. Here are a few websites showing some schist colours: https://www.worldofstone.co.nz/stone-mason/stone-masonry/schist https://wanakastone.co.nz/style/ Also consider the visibility of your mortar and its colour. Keep in mind that depending on your render system, you may be even more restricted in LRV, as some systems require an LRV of no less than 40%.
