I’m with Sonia. For me the tiles date the kitchen and the worktops are probably showing their age. If you can afford to replace them it will transform the kitchen and might well cost the same as professionally refinishing the doors. And I also agree that painting cabinets is best left to professionals but you could change the wall colour to make the room feel different. If it were my room I would try to find a Quartz worktop (try to find a warm colour as very white could make the cabinets look old) and I might well have a worktop splashback instead of tiles. And then you have a neutral kitchen and can apply almost any wall colour. Choosing this is easy- you either choose a colour consistent with other colour choices in the house or you pick a colour from the rug. I like Daisy suggestion of a soft green wall colour (but only if the blue tiles have been replaced.)

I think your kitchen looks timeless, but the idea of dark handles to match the chair legs would pull it together and the Roman blind idea is also better. The cabinets could be painted, but it’s important to have an excellent job done, otherwise it could easily be a bad decision. I’d want to have my bin in a cupboard too. The idea of a bigger glass door would be great, if you aren’t going to extend in the future, otherwise not worth the expense. It might be good to have a cheerful cloth on the table, that echoes the Roman blind and possibly a rug under it, which would zone the area, but it seems a “busy” view into the hall, would it be possible to have milky glass doors to keep the two areas out of view from each other, without loosing light? The paint colours on the walls could be changed to zone the dining area from the working area too and more pictures/hanging plates always cheer up bare walls, but that’s just my views, whatever you do, it’s your home, nota show house and you’ve got to live in it, so whatever you choose, will be right for you.

Sure! There are many different ways to develop a harmonious colour palette in a space. But in a kitchen of all places, I would want to measure the colour attributes of impactful key fixed finishes and take those into account too. e.g. worktop & flooring. Whatever colour for cabinetry and walls you choose, they need to relate to these major players of the space. Mapping into which Hue Families they belong, is a great place to start, before introducing more colours. Limiting the number of Hue Families from which you select these major items, is a stramlined way to ensure a sense of harmony in your space. Then you can add as many further colors as you like, including pale, muted, vivid, dark options - but only drawn from these 3 x Hue Families, keeps your colour palette cohesive. Example Hue Families that can work together and incorporate your window colour.

I think the mixed tiling is just too busy and will create clutter. By all means have a Moroccan tile if you wish but something less hectic would be better. The orange walls will just create too much drama and make the room even darker. If you want orange then tone it right down to a peachy pink. It will still be Mediterranean but not so in your face. However, once you add morrocan tiles you won’t need to paint the walls unless they need doing. The first pic is Zelig tiles which have a lovely pearlescent handmade finish. Less is more.
