Colour advice for kitchen cabinets and walls (picture incl)

[Carm10]

I wrote a thread about this before, but i got caught into other matters and never got to post a picture.
My kitchen is north facing (extension with velux windows) and the walls are painted in Crown Magnolia. It needs a revamp. I thought of a warm grey to go with a kitchen dresser we have (Egyptian cotton or pebble shore?) but grey is in his way out and it would not probably suit the creamier colour scheme of the tiles in the wall and floor (or would it, if grey is a neutral?).

As you can see my understanding of colours are zit

Then i thought ok, something creamier, but without yellow or pink undertones... maybe jasmine white or timeless? But these are nearly white so, what i would use in the wall (im sick of magnolia all over this old house), and the door and skirting boards??? And the accent wall that is currently painted in a sort of purple? My brain goes into overload. It can't take so many possibilities, so many colour combinations. I know when i see something elegant but i don't know how to remotely get there. I cannot continue procrastinating this matter. I remember as a little girl listening to women talk about colour combinations and i thought it would come magically with my period or something...
Nevertheless, let me know your thoughts. Im looking at Dulux mostly because the only shops allowed to open around me (bm, the range, etc) have Dulux so it will be easier for me to get samples.

I would use the colour of the grout between the tiles as the colour on the walls.
I'm not sure if you can get away with a stronger colour than that, there's a lot of different tones of brown in there.

i think is white grout. i was thinking to maybe paint the cabinets on the colour of the lightest tiles.

Why don't you paint your tiles? Thing is, because you have beigey coloured floor tiles I think you're going to have to stay on the warmer neutral side, not grey. What about Timeless type colour on the tiles and Natural Hessian on the walls? Are you painting over the purple wall?
We had stained wooden doors, and at the start of lockdown I bit the bullet and painted them white. The difference is unbelievable. You need a primer like Zinsser BIN to put on first. (I'm talking about the room doors, not the cabinets BTW).

I would paint the tiles

I dont think i can paint the tiles, they are irregular and textured. That would also add a fifth colour to choose and to get wrong (cabinets, trims and doors, walls and accent wall). How do people choose their colours? I go to deluxe website and i chose a white, a neutral... but i just feel i choose these colours randomly and i wont know if they go together until i paint the room ( i bought some samples to paint the living room and it looked greyish on the walls, when i finished the job it looks not blue). I just look at it on paper and i dont know if a colour has cool or warm or red or purple elements. and i am not colour blind.

i thought pebble shore was a warm neutral, thats why i thought it would go with the orangey, reddish, pinkish wall tiles.

Thats it. Everything stays as it is until i win the lotto and can afford an interior designer i wanted to do a little project to distract my mind and to help with mental health but this is just overwhelming and making feel very stupid that i cannot even chose 4 colours that go together.

I think just work with three main colours.
So,you have the units and door in a dark brown (and some tiles).
The floor a creamy colour to match some tiles.
Then pick another of the tile colours you like so you're working with three,so maybe an olive green.or the purple coloured tile and go for that.
It took me ages to find the paint to go in my tiny kitchen and it really does stress you out! Good luck,i'm sure it will look great
