Hi Brett about 5 to 10 years ago the trend was if your design style was contemporary your trim colour was the same as the walls and if your design style was classic your trim was a lighter, often white contrast to the wall colour. These days the trend is to the latter regardless of your design style as your builder's designers suggested. However matching your trim colour to the walls is still a good option if you have 8' ceilings. As there is minimal difference (only in the level of sheen) between the skirting boards and wall colour it makes the ceiling look higher. Another option is to do the trim in a similar but lighter tone such as Dulux Grey Pebble quarter. This is a very subtle tone on tone look. Whatever the colour, do you have a choice in the sheen level for your trim? I generally recommend semi gloss enamel on trim unless you are after a more classic look and your woodwork is in very good condition (the higher the sheen level the more any imperfections show up), in which case you could consider full gloss enamel. At the end of the day it's your home so you should do what you'd prefer - after all it's only paint so it's easily changed! All the best with your build.

I favour stone against cedar wood tones. It's a cool neutral and usually contrasts with the warmth of the cedar beautifully. It also creates a neutral backdrop against which you can accessorise and change to your hearts content without needing to repaint. Here's some idea's from Taubmans site.... https://www.taubmans.com.au/homeowners/colours/colour-trends I would probably go platinum or pebble half. Although those colours look heavily pigmented on a chart, against the richness of cedar they would appear very pale but not as stark as a white. It's also quite period correct and easy to live with.

I would not paint that wall. Instead I would install a rectangle huge colourful painting. This will bring interest and texture to the whole room. If you are thinking of going grey, then would it be a feature? Would anyone notice? Your home is quite subdued in the colouring....maybe some colour may pop on that wall instead of more subtle tones.

Hi, I agree and that it should be the ceiling colour but you could do a lighter shade of your wall colour for your ceiling colour (including the bulkheads) instead of ceiling white. Use Snowy Mountains Quarter. You will have a lot of shadows and less light on the ceiling, especially with the bulkheads, so a slightly lighter colour will help with that. Nice choice with wall colour btw. Rebecca
