I found a website that might be quite helpful for you http://www.colourtouch.com.au/ to visualise what colours and finishes could look like on your house. You can choose a style of house that closely matches yours then choose a number of set schemes, or start with a blank canvas and play around with any colour / finish you like.

what a great looking house...could you have the dark colour around the front porch, front of the garage and the alfresco walls (where it's shady in the photo) and have the rest of the house white or surfmist?

I am currently living in a rented house with beige tiles and similar walls. They look fine during the day but very sad n dull in the evenings. Better have a look at some display homes with similar tiles to yours in the evening.  Good luck ὄD

Thank you Dreamer for your comments. Good suggestion about the down pipe - hadn’t noticed that option. This site is so good for seeing things with fresh eyes. Attached a couple more photos to give an idea of the area. Looks a bit of a mess due to the renovations.
