With the curves in your couch seat, I'd prefer to see your stripe fabric in throw pillows and a solid used for the couch. I don't like how the stripe fabric cannot not line up from the seat to the banding on the curve, I'd use an aqua on the couch and the gold and stripe for the pillows.

something round, or that has curved lines. the last one's the most $$$, but oooh, it's pretty.

Post pics here ...and if possible photos of where you plan on using it

I have a few suggestions. Hope these will help. Go for a wooden sofa set. I know many people nowadays tend to go for fabric sofa sets and sectionals, but i fee that wooden sofas never go out of style. Also, you can change the upholstery colour any time if you want a more colourful look or a colourful slip cover (you can get a local uphostery guy to custom stitch one) which can be washed easily. Go for sleek furnitures that are not heavy. You can also add a few accent furniture pieces like an accent chair if the space allows for it. There are couple of things to note when you bring in colour. Choose one primary colour and maximum two secondary colours. See these links to [pep up your space[(https://www.houzz.in/magazine/is-your-living-room-too-brown-here-are-8-ways-to-pep-it-up-stsetivw-vs~101141558) and liven it. After you choose your colours, pick your decor. Add dashes of these colours through cushions, vases, flowers, paintings, figurines, curtains, carpets and other decor pieces. If you have a favourite painting, pick your accent colours from them. Or if you like the colours in a particular cushion covers, the other pieces can be colour matched. Always hang your paintings at eye level. I noticed that your hang your frames quite high up. Place them around 57 - 60 inches from the floor. Hope I could help
