I think the problem is that you’ve got a combination of cool colours (blue/grey), mixed with warmer tones (wood/beige). My Dd has taught me this. But some blues can be warm, (ie blues verging towards purple)
So I think it would all ‘come together’ if you went down with either the cool OR the warm colours, not both.
I personally dislike the cabinet colour and dark tops.
I would spray/paint or replace the cabinets, doors only. Replace the counter top. Maybe even look into painting tiles/or replacing. I’ve heard that tiling onto of tiles is very easy. Problem is that there is often an order of work. I don’t know if worktop would have to be after retiling it or not (but I’m sure there are work arounds.
I would definitely recover/paint the tiles on corner wall, even if I left the tiles everywhere else.
Blue isn’t a favourite colour of mine in a kitchen, but I think if you match the cabinets to the tiles it could look good.
Ref the floor which you say is beige. Id look at getting a hardwearing rug or runner that ties to cabinets or worktop or tiles. I’m not sure what shade the walls are?
I would do the two things that I don’t like whatever the scheme, in my case it would be cabinets and worktop.
Then sit back and see if you can live with it. It may give you enough breathing space that you could redo other parts in a few years.
Id look on Pinterest, you can search for blue kitchens. There lots of inspiration on there. Also many kitchen companies do their own planning/visual kitchen guides. Try IKEA?
Dont forget lighting and plants can make anywhere look better.
