My personal choice of colour palette frequently ebbs towards darker, richer tones, particularly during the winter months, because these tend to evoke a sense of cocooning warmth and comfort. This dark and alluring charcoal-panelled hotel room I recently stayed in creates instant drama, whilst contrasting crisp white bedding elevates the scheme further.
Regardless of the size of your room, the space next to your bed needs a surface, a drawer and a shelf to house what you are reading. A chair to put your clothes on of any size, two if you are sharing! A full-length mirror either on the wall or behind a wardrobe door if space is at premium. Light for reading and more to see properly in the dark of winter. A mixture of old and new always adds softness to this room, your sanctuary. And importantly a blanket for the all-important siesta without disturbing the bed.
