Thanks for your reply. The roof is prominent. After a lighter and slightly warmer option for the wall. I like white but there are so many shades of white. Which one to pick that will give a little depth without being too creamy.

Have you been to visit some kitchen showrooms? You can customise the photo search here on Houzz quite a bit. For example, you can simply select [dark wood[(https://www.houzz.com.au/photos/kitchen-design-ideas-with-dark-wood-cabinets-phbr1-bp~t_10444~a_17-103) cabinet finish in the filter options. Then add more filters like floor colour, kitchen layout, cabinet style, wall colour etc if you wish. Leave the benchtop and splashback options open and see what results you get. You can then save any photos that appeal to your ideabook.

Match to garage roof colour. Maybe a 'timber look' panel lift door. Matching to the facade could mean a mismatch of similar colours hence my suggestion of roof as its close by yet far enough away.

You should do a google search of “ teal headboard “ and there are many images which should help . Similar shades to those Dulux ones will be there . When your bed is ready , paint a few shades in strips to see what works with your bed head and carpet .
