Leaning toward BM Hawthorne Yellow or Weston Flax for entryway, living room, and Kitchen (since it's all an open space). Beachnut Lane: Soft yellows from Benjamin Moore~ Hawthorne Yellow, Weston Flax, Concord Ivory!
Blue Yellow Gray Colors - our bedroom! Painted walls grey, white bedding with grey sheets, yellow shams, yellow throw. and tied together with our black furniture. Slowing adding blue pops and art/photos for walls!
Place painted foam board in the back of the bookcase, giving the look of a painted bookshelf w/out the commitment. Love this idea for a small book shelf next to couch. Good way to use yellow without committing to it in a big space.
