I don't know how hot it gets in Auckland in summer (I've only ever been to NZ in winter!) but if it gets hot, then go for a pale colour. Dark roofs should be kept for cold places!

You are so right white is never out of fashion. I would set your budget and then look at your options. If you plan to stay in the house for many years then spend to the top of your budget (if that is going to give you a life time of pleasure), if you plan on being at the home for only a short time / few years then I would go mid range so it looks lovely, will have good resale value but you can invest your well earned money to go towards something else as well. Obviously Marble / Granite is the top of the range but there are so many cheaper and very attractive options these days that look just as good.

meager light in the kitchen, trying to find paint colors that would brighten it up, I was told whites would not work, I changed the old dark brown flooring to light flooring and now it looks bad big mistake, the kitchen doesn't look anchored, with the light floor, I need some ideas to make it feel anchored again, would dark cupboards work, sorry for lack of photos. Some suggestions would be great

The roof will be a dark grey/charcoal colour. The gutters are an off white colour, windows are white and we have cream brick all the way around. I am unsure what colour to paint it. I want to keep away from green because my house is surrounded by a sea of green. My husband thinks a light grey along with a new timber front door.
