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!

Something like this would be great!

Hey there. Go for a cooler colour palette and draw the eye to a focal point at the end of the hallway, a console table, artwork, a mirror etc. A cooler paint colour helps the small space visually recede. In terms of the doors, going slighter darker will again make the space feel bigger. Go half a shade lighter on the low ceiling than the walls, using the same colour, rather than bright white, which will look dirty in the low light. Good luck!

Looking to repaint our house. Love to hear any ideas for paint colour that will suit the buttercream joinery... plus the base, do I try to match the roof or do same colour as whole house....
