I LOVE all the colors you've selected, but I think that they might be a shade too pale....consider going one shade deeper on the color strip. also, keep in mind that the shades with a little blue in the base will actually brighten up the space better than the green based shades (look at 'rhine river'). i'd love to see you: remove the dated vertical blinds and replace them with simple straight hanging curtain panels (white?) layered over simple, inexpensive matchstick or bamboo shades; use larger lamps with drum shaped shades, which are so much more modern looking; and add more and larger art which will A) coordinate with the palette of the space and B) offer some of your personal style into the space. keep your sofa neutral in color....this way you aren't locked into a color palette, which you may one day wish to change.....you can never go wrong with a medium range shade of taupe! an area rug will instantly cozy up the space and will look more "finished". so much great potential! please update us with your choices! have fun with it!!

Hi! I always recommend purchasing an accent piece first before painting to see how you like it in the room. Here are a few ideas:
