Hello, What a lovely living room, we love the fireplace, and even that you say that it doesn't get much light the windows look big! We would recommend you to keep the colour of the walls light, you could go for a very light grey (or even a white) to inject more light. You can then play a bit with colour with furniture, accessories, etc We are a small online design company that offers impartial, good value design advice. If you are interested we could work on your design with you and send you a moodboard with all the elements that would help you to visualise the space. Have a look at our website and let us know if you are interested! Our packages start at £50 per room. www.lucianasanchez.com

I know it's counter-intuitive, but I'd go deep saturated Blue/green...or Teal. All over. It will unify all the odd planes and angles in this room. Keep all the woodwork a fresh white. Use pops of jewel toned soft furnishings...to link the blue & taupe sofas...or... Use patterns in tribal/ ikat tones to keep it masculine. Build up some open shelving for storage along dead-wallspace near the door entrance to this room.

F&B Skimming Stone?

If you do find it a little top heavy, I would be tempted to soften the green colour very slightly - have a look at earthborn colours they have some lovely ones I think you'd like, Sunday Stroll and Gregory's Den being the best I think for you. If it helps, really think about how you want the room to feel when you're using it, light and airy/statement and impactful/calm and relaxing/luxurious and elegant/industrial and rugged? - that will help you dress and finish the space too if you keep this in mind whilst choosing your finishes. The tiles have a yellow undertone to them and the gorgeous, sumptuous green colour you have chosen looks like it has a slightly blue undertone so it's just a case of balancing the two so that the walls don't overpower your cabinetry :). If you're happy keeping the heavier green maybe tint the ceiling colour with green, just a touch to soften the ceiling line? Exciting project! Good luck!
