I agree! Go for what you love. Down the track at resale time, if you feel it's too dated then, there are many splash back materials that can be applied right over top of tile. Is it just the area behind the cook top that will be tiled? I think anything will feel like "too much" at first if you've become accustomed to how it currently is. It's like when you paint a room. It can feel overwhelming at first until you begin to put furniture and decor back in place. A simple way to trial colours is to tack up some wrapping paper, fabric, contact paper (backing left on) or whatever you find that has a colour you think could work. Try use things with different sheen/gloss. Even paint a board and prop it there. Leave for a few hours and see what does and doesn't work for you.

I'm going to suggest these grey Montage tiles. I think the Como tiles are nice too. Dark grey will add drama and balance out the dark sink. The mixed tones will tie in the variations of grey and silver in the bench tops, appliances and glass door frames. The stone/slate look will add a natural element to complement the wooden floor and balance out the laminate. If you do go for colour, I like Bernadette's suggestion of complementing the glass colour. A tile that looks like pale jade might be nice.

Hi Hu, I love the window in your kitchen, if you go white subway tiles a stack pattern would add a contemporary look and white grout would give a clean and stylish look and blend beautifully with any decor items you add.

Using the same material as the bench top gives a seamless look. In our recent Reno we went from a glass splash back to caesar-stone the same as the bench top. Just as easy to clean as the glass. It looks beautiful especially with led lights under the overhead cupboards to create a feature wash of light down the stone. We also used the same material on the ledge in the adjoining dining - just a small change but it really ties the two spaces together in a subtle way.
