thank you Louise for your coment, much appreciated. Island is a grey colour and can't remove the cover yet as it still needs protection.
I love colour so other pieces in room will be strong. May not even notice the tiles 🤔

I love the tiles and the base cupboards. I am not sure about the brown above the blue but if you love colour (I do) and are going to have strong colours it may all come together. At the moment you are only seeing it partially done. I would say wait and see. But ok Louise has a good point.

With everything being covered in builders dust, it's hard to see what colour your floor, wood, benches are.
Could you take the, not so protective, cover off the bench, just to take a photo?
You chose that tile for a reason. Did you have swatches of everything at the design stage, and were happy to proceed?
The colour of cupboards appear pastel green and the tiles pastel blue. Are you going for a mid century vibe?

Wait until everything is clean and finished. Then reassess.
Unless you are 100% doubting your choice.

If you think you’ve made a mistake, you’ll always look at those tiles and wonder what could have been. I’d change them now. It’s not a huge area, so hopefully a reasonably small expense for some peace of mind.

Just in perspective of your challenge. This is a kitchen disaster.

Well i can't argue with that, must admit 😉

No no... don't worry it will all be fine. Just keep going and don't second guess yourself! The lovely thing is that you have predominantly blue shades which in my experience always look good, in decorating the space, and perhaps even painting a feature wall another shade of blue (perhaps with some grey in it to match the bench) it will all blend beautifully. With texture added in tea-towels, and cups and bowls it will all look lovely. Remember how cluttered a kitchen can get, it won't look so stark soon enough. I'd put a pop of lemon yellow, like a fruit bowl and mugs. If it helps, I am actually using blue throughout my house and at first I thought I'd have to carefully choose shades, but I am finding it all looks great and the various tones actually add depth and interest. I was worried because there are open plan areas with different blues and from one space to the other you can see them, but it all works fine so far. I've even gone so far as to combine paints for custom blends. I just go bolder for smaller spaces and tone it right down in larger areas and it seems fine. I used dulux duck egg blue in the kitchen which is a lovely soft blue, with hints of grey and green. I have a vibrant vintage cabinet for tea things in a bright teal blue. There is a hideous stainless steel splashback I can't change till I can afford to have the asbestos cladding removed so this is all temporary for now, but it makes such a difference and it was worth a little touch up to freshen it up till I do it all over properly.
