Need suggestions for wall paint that pairs well with turquoise dining room and charcoal sectional in open concept living room, couch appears darker in photo
You will need to post a photo of the turquoise dining room. Hard to make suggestions without seeing that.
Weird section of wall - paint it ceiling, wall, or trim color?
Which fabric do you like best for a sectional sofa?
what color rug would go well with grey couch and red lounge chair
What shape and color sectional for this space?
Something light and slightly cool to work with your rug like Sherwin Williams Opaline is what comes to mind. And to look more pulled together consider adding that teal/green tone in accents in the living room (throw, pillows, art).
