I must admit I know next to nothing about decorating! I'm assuming my sitting room is north-facing as it gets bugger all natural light, yet my kitchen which is on the other side of the house is lovely and bright.
I currently have plain textured wallpaper in a grey-beige/mushroom colour but this is too dark for the room and makes it feel even gloomier. My kitchen is a muddy olive green colour but it looks okay because of the light it gets (v. small house, literally tiny square hallway behind front door, sitting room, kitchen and small loo downstairs).
Ideally would like to paint the same colour throughout downstairs but I know colours can look different in different rooms. Looking for a pale cream/off-white colour, warming but wont give the room that yellowy tint... I know I'm asking a lot!
