Adding: I’ve been looking at Stardew, sleepy hollow and languid blue by Sherwin Williams. Blue Porcelain by Benjamin Moore. Stardew I am worried will look grey.

I used BM Yukon Sky for trim. The walls are more blue than they appear in the photo.

Lovely, but, assuming the rest of the house does not have blue trim, how do you plan to meld it from one door frame to the other? Consider that before you bite the bullet.

Sleepy Hollow is going to go baby blue on you.

Stardew is a beautiful color but can look very different depending on lighting. We have used it twice and the outcome was different

here in the dining room more baby blue

Here in an office more subdued

but i think it is worth a try. I would look at

SW Delft

SW Languid

BM Nantucket Fog

BM Province

BM Van Courtland Blue

BM Waters Edge

Youre going to have to sample in your light.

@Design Interior South thanks so much! That is a really lovely blue- it looks so much more grey on the swatch i have of it. I actually just had narrowed it down to languid blue and niebla azul! Have you ever used either of these? now im wondering how accurate the swatches are

Anyone used Niebla Azul? my painter is reccomending this for the trim but not sure if it leans very light blue or light grey? i want it to look blue!

@Design Interior South oh wow it looks so different than the swatch. Would you pick niebla azul or languid blue for the trim? it is for a southern coastal home that leans a bit traditional. the walls will be alabaster.

I recommend you get samples. Paint looks differnt in every space. Lighting and the influence of floor color, outdoor surroundings etc all reflect how a paint color is going to look in your space. They are all beautiful colors. None of them are going to look exactly like they do on the paint chip as they do on your trim. Go down and buy minimum 3 maximum 5 sample pots of the colors you like the most and paint them on the trim. You should know pretty quickly which ones you like and don't. All of them will work in a coastal home.

These are AI so they will not be exact but

Niebla Azul paired with Alabaster

Languid paired with Alabaster

What are your deocr and furnishings? Do you have fabrics you can pull a blue from?
