Below is Sherwin William’s Arts & Crafts colors with suggested accents (other paint companies might have other chip suggestions?). I like to have my whole house color-cohesive. Let’s say in the living room I chose a dark blue for all 4 walls. According to SW’s A&C palette, Bunglehouse Blue pairs nicely with Indian white and Classic Light Buff or in another chip they pair Bunglehouse Blue with Antiquarian Brown (looks rust-like) and White Hyacinth. So, taking my cue from that, I’d paint adjacent rooms in one of the whites or Light Buff. And in each room I’d have accents of dark blue, white, Buff, and Rust.
