Thanks for all of the suggestions everyone. Given me many ideas to think about

Hi there, I would be thinking to go for white cabinets and walls,with white appliances that you plan on Keeping or can change to stainless, your choice of benchtop. as this picture shows the timber door frames etc will then fit, White cream and timber should blend in with the floor tiles, maybe even the blinds will look ok, photos help

Teal works really well with dark chocolate brown and beige (greeny blue teals with deep brown leather sofas or tables and caramel walls pop and yet are homely and comfortable) so a rug underneath the table and sofa to delineate that space with teal in it or all teal (I would go for a pattern as you have very neutral pieces the one from Kathy above with caramel and beige is perfect I think) could work -ditto curtains and cushions. Given the neutral pieces you could add pops of another colour depending on the teal tones you use. Also lighter turquoise tones that sort of layer with teal - its deeper cousin.... a turquoise ceramic (or other objects) with a toning teal one ( teal and turquoise can vary on the blue-green spectrum) and a lovely caramel coloured piece ( things work well together in 3's I find) all of varying heights shapes and some texture on at least 1 - would look great somewhere. Burnt orange (a more subtle tone than hot orange) can be a great and more adventurous addition as can khaki - just keep them subtle and mix it up. I have a great market bought cushion made from an old woollen tartan type blanket of aqua /turquoise, a light khaki and burnt orange with a caramel leather cross on it that looks so good on my dark brown leather sofa (sorry no photo on me).

Hello again, thank you for the input. I've taken it all on board. Regarding the island, we will be sticking with Knights Grey but if we choose a very dark floorboard, we will then switch to Timeless Grey (which happened to be one of the swatches I'd picked up anyway!) to avoid that sinking effect. Thanks for the tip. I won't be able to get back out this week to check the Dulux Raku colour, did I mention that I'm getting around with a 1 month old and 2 year old? They are totally dictating my schedule! Ann I'm not sure exactly how they get half strength. I just have the understanding that paint looks darker on a wall than it does on the sample card so to always opt for a lighter shade to counter that effect. So to avoid the Snowy Mountains colour looking too dark, I will go for a half strength. Worst case, I figure, is that it will just be a touch lighter than what I'd expected. There wasn't consistency between the three separate Snowy Mountains cards that I ended up with so I guess it's to be expected anyway. Thanks for sharing your experience Antonia, it's good to know it works. Today I went out to Beaumont Tiles to try and find a tile like the one I attached to my original post. This was surprisingly difficult to match and I've borrowed a sample of the closest match from the store to mull it over. The colour seems to work quite well against all my samples but I'm worried about the wavy edge and how it will appear on the wall when grouted. On the one hand I'm worried it will look too busy or untidy, on the other hand I think it could be a winner because it could add some depth or interest to an otherwise boring subway tile splash back. I've attached the tile against my samples and also Tranquil Retreat (half strength) wall with Vivid White trim. Please tell me what you think :)
