Embrace the arches and keep it light, but add some contrast. Paint every wall with an arch in it fresh white, all ceilings too. Paint the adjecent walls a soft color. For example; when you keep the kitchen tile, you could paint the walls above it a soft pink or mauve. I see three open areas, so you could divide those with three soft colors and white inbetween. Keep most lights simple and functional, uplights will enhance the arches, glass pendants will add warmth. And I think a soft olive or sage green is a great color for a living room.

I would like to add the floor will be Mahogany Color Wood Look Tile.Very dark.

pendant lights looks nice only if place above a table like a breakfast nook or island. hanging them freely does not complement their look. since there is no island under the ceiling try to embed recessed lights in the ceiling. alternatively track lights will also look great if you need brightness.

Seven Herbal. You may have to share the floor plan and few pics. A lot depends on the brightness of the light as well. Please share those details. Thanks, Nitin 888.4851.444 Cornerstone Designs Bangalore
