any ideas

The color currently on the trim/doors is what needs to inform the color of white on the walls.

The standard option is to use that color on the walls too..... just in a less shiny sheen, like a matte finish.

Otherwise, the white for the walls either has to have more chroma or less chroma than the trim. Because that's how you ensure one color of white won't make the other look dirty or dingy. The guideline is a difference of 0.20 +/- in Munsell Chroma.

You can look up Chroma values for all major paint brands on the Paint Color DNA Table. You want the column named "Chroma".

Sorry I see nothing thta says coastal to me in your space . I do agree if going white then the same color as the trim but in amatte finish Mixing whites is tricky always.

Definitely something in the white family. Pale blue is always a great color to pair with white for a coastal theme. Good luck!

Yes, white is the way to go. Put your samples next to your cabinets so you choose something that will go with them and won't drive you nuts. I'd stay away from blue undertones. You need something brighter and softer.

The home seems dim and very dim. White may NOT be the way to go. Consider all of the desired coastal ......first.
