This north facing study has minimal natural light – with the need for articial lighting during most of the day. For dark rooms – I am a great fan, of working with what you have ie not trying to make the room light and airy as you will never be able to achieve this. Then you have the added issue of which dark paint to go for? The problem with these dark paints is that they tend to show every mark – fingerprints, liquid splatters etc etc…. You really do need a high quality paint in these situations.
I always use Fenwick and Tilbrook – they are superb with extremely high pigment levels. The customer service is second to none as well. For this design proposal the Still Norfolk colourway is used from Fenwick and Tilbrook, Linwood Niva fabric in the blind – you can see the blind in the finished room here.
