When deciding the overall colour scheme for a particular room don’t be tempted to choose the  colour for walls, backgrounds, ceiling, doors first. There is such an abundance of colours, textures and shades to choose from, and paint is relatively inexpensive and can be matched to almost any imaginable colour you eventually decide on. Instead begin your colour search with those elements that are not so flexible. Look at the fixed elements like furniture, tiling, wallpapers and fabrics. Base your paint colours on these.
