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.

HI RinaI do agree I love jewelbox rooms, but I consider them more cosy ... and with a grey marble floor it goes all Versace Italianate! I am trying to balance the colours by bringing in a pattern on the covers rather than plain. I feel this will bring colour without overpowering the room. In the pictures I showed above, the rooms are basically neutral but the colour is brought in via pattern - I think this might be the way to go...Ideally a green or blue on a subdued grey would be the best, but I dont know what the market is like for Sumit...Cushions can do a lot to tie in the other white/grey elements.Shelley - navy is a good suggestion, but as Sumits area is quite tall and thin, trying to keep the general area light Any more suggestions most welcome. These are just ideas after all and Sumit will choose what works for the room in the end ;-)

You could use a cupboard to hide cabels, and, 2 in 1, it decorates the room AND hides cables. You can't put the cupboard to touch the wall because the cables block the cupboard to touch the wall but, who cares?

Depends on what effect overall you want -- hot tropical feel (oranges and reds) or a bit more toned down? You can take inspiration from pictures of gardens with lime green heuchera or sweet potato -- often paired with chocolatey purple, silvery greens and blues.
