Ahhh... I sort of understand now. Are you planning to paint only the wall with the blue line or all three walls in the space? I wouldn't stop the paint as you suggested unless you do some kind of fun painting technique like this... but without knowing where that wall goes, it's hard to give advice on where to stop. I think a nice color on the wall could really frame the kitchen area. Or you could paint just the wall with the window which would be an obvious accent wall.

Nope it’s not egg shell either. This is nuts.

it all depends on what you do w/the paint, trim and the door. many combos. Revere pewter trim and doors, white walls Revere Pewter walls, White trim, white doors White trim, dark door (SW Dovetail) I like this combo,,,slightly darker door, white trim White door, white trim, griege walls (pale oak and white dove) Everything one color darker doors, white trim SW Crushed Ice, White trim/doors

Wall color but also ... Would seriously consider adding a faux skylight there or artificial skylight lighting. https://www.lightology.com/index.php?module=coelux-artificial-skylights https://www.google.com/search?q=faux%20window%20night%20sky&tbm=isch&tbs=rimg:CRMQCYIJL-p3YSJT2IaEA5xP&client=firefox-b-1-d&hl=en&sa=X&ved=0CBsQuIIBahcKEwjQwtaewonyAhUAAAAAHQAAAAAQCQ&biw=1349&bih=615#imgrc=l1JjJXkmXPfQpM
