I wouldn't worry too much about trying to match your tiles with your carpet, dark grey will go with most colours plus the bedrooms are separate rooms, and sometimes it's better to contrast particularly given they're two different surfaces anyway... my biggest no. 1 question before colour would be what sort of tiles are you after, ceramic, porcelain, etc? Cause that is a massive area you're thinking of tiling and the cost differential could be considerable

Before deciding on a colour, don't forget to consider your kitchen cabinetry, benchtop, splashback, etc (and dining furniture)... for example, if you have a classic hamptons (farmer style) kitchen (and furniture) then don't discount a warm white for the walls... it won't look clinical as the warmth will come from the kitchen cabinetry, etc and dining furniture, e.g. But if you have a "hamptons inspired" look with a slightly more contemporary kitchen cabinetry (and furniture), then in my opinion (all nice options above but a bit too beige'ish for me) so I would suggest a light shade of a warm grey e.g. Whichever way you decide to go, try to narrow it down to 2-3 colours, get the small pot samples and paint each one on all the applicable walls as they will all look different at different angles depending on how they reflect natural daylight and the lights at night time... then you may be able to make a clearer decision. Good luck! :)

The dust and work boots coming inside the farmhouse used to drive my mum nuts! If you know the brand and name of the brick, do a google image search to look at some of the new builds. That might give an idea of some possible colour schemes that could work. Many new builds have painted rendered portions work well with the brick colour. You could use one of those colours for the verandah or posts, for instance. The main difference in the newer builds is they tend to have a contrasting mortar ie. darker bricks with light mortar.

Hi ucheokeke1 colour matching to the tile should be relatively simple as already explained. However even if you find the right paint colour, unless you ask for optically clear glass (known as Starphire glass in Australia) your colour will be skewed by the natural green skew of ordinary glass. If you can source a coloured glass splashback that's close to your chosen colour from a standard range you will be OK with normal glass. If there is nothing similar in a standard range, the only way to ensure true colour representation is to pay the extra for optically clear glass. I hope this makes sense.
