Hi, your home looks pretty good, you have done a lot on the interiors. Coming back to the question, yes, you can add a wallpaper behind the television, go for a textured wallpaper as it will create a compliment to your television. As you have decorated with wooden elements, you can go with a bookshelf on the wall. And, there is one more thing which will be a simple addition but will look perfect and that is an antique wall clock. An antique wall clock will make your wall look great without any fuss.

I agree with Billmore Homes paperbark is a very nice colour and goes well with Jasper http://colorbond.com/colour?Category=4969402186C2455AB302B1ECD6FE7176 The idea to use double strength is good for outside projects because the light can affect colour so much at different times of the day. Soft greys are back in fashion too so don't overlook Ironstone, Basalt and Wallaby( the web link shows what I mean by those colour titles) if you are stuck with the blue door it can be hard to coordinate with blue but you can alter its shade slightly by a freshen-up coat of the original colour or a tone or two darker or a few drops of black (and I mean drops) is amazing the depth it adds to a paint tone without changing the overall colour.

I have a house that is tiled in a multicolour slate tile all through the living areas. The house was built in the 90's and was only 4 years old when I bought it in 1996. I am assuming your tile is also a natural stone?? if so it will need sealing as they are porous and may need resealing down the track, we have only resealed our floor once. Make sure you keep a note of the brand and type of the sealer for future reference.I would not take it through to the bedrooms - too much. The floor is very forgiving of dirt, dust, food splashes etc, if you have a busy week and don't get round to washing or vacuuming the floor no one will notice. The multicolour will work with your hamptons inspiration, careful choice of wall colour is needed, you may need to have the floor laid before you make a final choice to see what the colour it throws. A wall colour with a slight hint of colour works better with the multicolour than the bright whites or yellow whites. Hope this helps.

The silver will look quite good with your colour scheme. I would probably change some weatherboard for Scyon Axon just to change it up a bit. Also use Scyon Axent for architraves and wall corners. Don't forget eaves and veranda ceilings, etc. as a really nice looking feature use HardieGroove or maybe even some timber to break up the acres of painted surfaces.
