This main area of house also opens to the kitchen. You can stand in each room and see the others. Very open.

All areas don't need the same color, but varying shades of it. Find one that compliments or even matches the green sofas, and work the entire color strip throughout your space. Put the darkest shades on walls that receive the most direct sunlight, and the lighter shades on darker areas. The lightest shade can be used on the ceiling if you like. Think of it as sort of color blocking but within the same palette. See pic #1 below for the concept. Blue, yellow, orange and even eggplant or purpel work well with green too, although I can't really tell from your pics what the exact green color is.
