Hi Sian! I would not recommend painting the wall red or green as per se. If you have a small room and furniture is red/green you need to be careful with wall colour, I suggest keeping it as neutral as possible. Soft/dark grey is a safe choice and looks good in contrast to red. It would be good to see the rest of the furniture for a better perspective, perhaps you can take photos with your phone? Check out the option below for colours. Considering your description of the room, I would think about Fashionable grey or Moroccan brown (disregard the blue and brick colours) ? See below the options, from this palette you can also think about grey owl or similar.

Front room for me! we have three rooms opened into one large living space, this is great when you have a large family. I still say front room, but mainly to describe the location of say my book or glasses if I'm am asking somebody to fetch them for me. It makes for a quicker find :)

Hi Zoe, Its tricky to se from the photos provided but it looks like the room has great bones and I agree a colour injection is called for, deep purple works beautifully with grey. I think by adding some great lighting and artwork you could really add some wow factor. I actually offer an affordable interior design service for people like yourself who need the help of an experienced interior designer. For a fixed sum you will be provided with a master plan for creating a professionally designed space that you can implement at your own pace. Please check out my profile for more information. Thank you Charmaine

Going for a white sofa would help create a light and airy living room. The white sofa would match the airy elements you already have in the room: the light pastel wallpaper and blue chimney heart, the white skirting, the light coloured wooden flooring. The black of the fireplace hearth can be tied together with details like black legs for the white sofa, black legs (maybe hair pin legs) for a white coffee table or for a cabinet (cabinets with legs look very smart: https://www.buzzfeed.com/alisoncaporimo/legs-for-days). Black cross legged lounge chair & ottoman in a navy blue would match the navy curtains. See through furniture helps for an uncluttered feel: transparent chairs, glass table, thin furniture legs, x leg ottomans. The window coverings also have to be in light materials. Consider introducing flowy sheer fabric with or instead of the navy curtains. White or light pastel coloured area rugs in the room and avoid choosing area rugs featuring heavy and busy patterns. Braided area rugs in pastel and light colors also make a good selection. Some pictures below:
