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.

this is the front and was thinking dark grey/charcoal for the side fencing ? There is a lot of timber fencing Will this suit the Lexicon half (cool white )?

Everyone has their opinion... I'm saying I don't like it. Others will like it. It's in comments above.

I really like the first picture, though it does look like it's due for a repaint, and while I like the colour scheme, if you're bored with it I suppose it's an opportunity to change it. In the second picture the green trim and the detail above the front steps stands out and looks dated, and the landscaping doesn't enhance the house.
